     TECHNICAL FIELD 
     This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that detect inputs for manipulating user interfaces. 
     BACKGROUND 
     The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects on a display. 
     Exemplary manipulations include adjusting the position and/or size of one or more user interface objects or activating buttons or opening files/applications represented by user interface objects, as well as associating metadata with one or more user interface objects or otherwise manipulating user interfaces. Exemplary user interface objects include digital images, video, text, icons, control elements such as buttons and other graphics. A user will, in some circumstances, need to perform such manipulations on user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, Calif.), an image management application (e.g., Aperture or iPhoto from Apple Inc. of Cupertino, Calif.), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, Calif.), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processing application (e.g., Pages from Apple Inc. of Cupertino, Calif.), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, Calif.), a disk authoring application (e.g., iDVD from Apple Inc. of Cupertino, Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, Calif.). 
     But existing methods for performing these manipulations are cumbersome and inefficient. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for manipulating user interfaces.

     DESCRIPTION OF EMBODIMENTS 
     The methods, devices and GUIs described herein provide visual and/or haptic feedback that makes manipulation of user interface objects more efficient and intuitive for a user. For example, in a system where the clicking action of a trackpad is decoupled from the contact intensity (e.g., contact force, contact pressure, or a substitute therefore) that is needed to reach an activation threshold, the device can generate different tactile outputs (e.g., “different clicks”) for different activation events (e.g., so that clicks that accomplish a particular result are differentiated from clicks that do not produce any result or that accomplish a different result from the particular result). Additionally, tactile outputs can be generated in response to other events that are not related to increasing intensity of a contact, such as generating a tactile output (e.g., a “detent”) when a user interface object is moved to a particular position, boundary or orientation, or when an event occurs at the device. 
     Additionally, in a system where a trackpad or touch-screen display is sensitive to a range of contact intensity that includes more than one or two specific intensity values (e.g., more than a simple on/off, binary intensity determination), the user interface can provide responses (e.g., visual or tactile cues) that are indicative of the intensity of the contact within the range. In some implementations, a pre-activation-threshold response and/or a post-activation-threshold response to an input are displayed as continuous animations. As one example of such a response, a preview of an operation is displayed in response to detecting an increase in contact intensity that is still below an activation threshold for performing the operation. As another example of such a response, an animation associated with an operation continues even after the activation threshold for the operation has been reached. Both of these examples provide a user with a continuous response to the force or pressure of a user&#39;s contact, which provides a user with visual and/or haptic feedback that is richer and more intuitive. More specifically, such continuous force responses give the user the experience of being able to press lightly to preview an operation and/or press deeply to push “past” or “through” a predefined user interface state corresponding to the operation. 
     Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, multiple contact intensity thresholds can be monitored by the device and different functions can be mapped to different contact intensity thresholds. This serves to increase the available “gesture space” providing easy access to advanced features for users who know that increasing the intensity of a contact at or beyond a second “deep press” intensity threshold will cause the device to perform a different operation from an operation that would be performed if the intensity of the contact is between a first “activation” intensity threshold and the second “deep press” intensity threshold. An advantage of assigning additional functionality to a second “deep press” intensity threshold while maintaining familiar functionality at a first “activation” intensity threshold is that inexperienced users who are, in some circumstances, confused by the additional functionality can use the familiar functionality by just applying an intensity up to the first “activation” intensity threshold, whereas more experienced users can take advantage of the additional functionality by applying an intensity at the second “deep press” intensity threshold. 
     Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, the device can provide additional functionality by allowing users to perform complex operations with a single continuous contact. For example, when selecting a group of objects, a user can move a continuous contact around the touch-sensitive surface and can press while dragging (e.g., applying an intensity greater than a “deep press” intensity threshold) to add additional elements to a selection. In this way, a user can intuitively interact with a user interface where pressing harder with a contact causes objects in the user interface to be “stickier.” 
     A number of different approaches to providing an intuitive user interface on a device where a clicking action is decoupled from the force that is needed to reach an activation threshold and/or the device is sensitive to a wide range of contact intensities are described below. Using one or more of these approaches (optionally in conjunction with each other) helps to provide a user interface that intuitively provides users with additional information and functionality, thereby reducing the user&#39;s cognitive burden and improving the human-machine interface. Such improvements in the human-machine interface enable users to use the device faster and more efficiently. For battery-operated devices, these improvements conserve power and increase the time between battery charges. For ease of explanation, systems, methods and user interfaces for including illustrative examples of some of these approaches are described below, as follows:
         Many electronic devices have graphical user interfaces that include various graphical objects and frames that are controlled by a confusing set of overlapping and sometimes conflicting inputs. The embodiments described below provide a fast, efficient, and convenient way for users to manipulate the graphical objects inside, outside, and between frames using inputs that are differentiated in accordance with an intensity of the inputs. In particular,  FIGS. 5A-5F  illustrate exemplary user interfaces for manipulating framed graphical objects using gestures on a touch-sensitive surface.  FIGS. 6A-6B  are flow diagrams illustrating a method of manipulating framed graphical objects using gestures on a touch-sensitive surface. The user interfaces in  FIGS. 5A-5F  are further used to illustrate the processes described below with reference to  FIGS. 6A-6B .   Many electronic devices have graphical user interfaces that include various masked images that are controlled by a confusing set of overlapping and sometimes conflicting inputs. The embodiments described below provide a fast, efficient, and convenient way for users to transition between modifying the masked image (the image mask and the original image concurrently) and modifying the original image corresponding to the masked image using inputs that are differentiated in accordance with an intensity of the inputs. In particular,  FIGS. 8A-8N  illustrate exemplary user interfaces for manipulating images and masked images.  FIGS. 9A-9C  are flow diagrams illustrating a method of manipulating images and masked images. The user interfaces in  FIGS. 8A-8N  are further used to illustrate the processes described below with reference to  FIGS. 9A-9C .   When a user is editing text in an electronic document, the user may wish to correct spelling of a misspelled word in the text, some applications have separate spelling correction interfaces that are accessed through a complex sequence of gestures or other inputs however these interfaces are cumbersome and inefficient for correcting spelling errors. The embodiments described below provide efficient and intuitive methods of correcting misspelled words in response to detecting a gesture with contact that meets predefined intensity criteria while a focus selector is located over the misspelled word. In particular,  FIGS. 11A-11DD  illustrate exemplary user interfaces for word spelling correction.  FIGS. 12A-12D  are flow diagrams illustrating a method of word spelling correction. The user interfaces in  FIGS. 11A-11DD  are used to illustrate the processes in  FIGS. 12A-12D .   Many electronic devices use graphical user interfaces to display electronic documents, some of which include sheets (e.g., sheets of a spreadsheet, or pages of a word processing document) however switching between editing the electronic document and templates for the electronic document sometimes takes a large number of distinct inputs that can be confusing and inefficient for the user. The embodiments described below provide a fast, efficient, convenient manner in which to determine whether to edit content of a field in a sheet or to edit default properties of the field in a template for the sheet based on an intensity of a contact while a focus selector is over the field. In particular,  FIGS. 14A-14N  illustrate exemplary user interfaces for editing a field in a sheet of an electronic document.  FIGS. 15A-15C  are flow diagrams illustrating a method of editing a field in a sheet of an electronic document. The user interfaces in  FIGS. 14A-14N  are used to illustrate the processes in  FIGS. 15A-15C .   Many electronic devices use graphical user interfaces to display user interface objects. Often, these objects are displayed according to a particular relationships relative to one another (e.g., z-order or text wrapping properties) however changing the text wrapping properties of a user interface object sometimes takes a large number of distinct inputs that can be confusing and inefficient for the user. The embodiments described below provide methods and user interfaces for changing text wrapping properties of a user interface objects in a fast, efficient, and convenient way based on an intensity of a contact while a focus selector is over the user interface object. In particular,  FIGS. 17A-17K  illustrate exemplary user interfaces for changing text wrapping properties of a user interface object in accordance with intensity of a contact on a touch-sensitive surface.  FIGS. 18A-18B  are flow diagrams illustrating a method of changing text wrapping properties of a user interface object in accordance with intensity of a contact on a touch-sensitive surface. The user interfaces in  FIGS. 17A-17K  are used to illustrate the processes in  FIGS. 18A-18B .       

     Exemplary Devices 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
     It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact. 
     The terminology used in the description of the various described embodiments herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad). 
     In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick. 
     The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user. 
     Attention is now directed toward embodiments of portable devices with touch-sensitive displays.  FIG. 1A  is a block diagram illustrating portable multifunction device  100  with touch-sensitive displays  112  in accordance with some embodiments. Touch-sensitive display  112  is sometimes called a “touch screen” for convenience, and is sometimes known as or called a touch-sensitive display system. Device  100  includes memory  102  (which optionally includes one or more computer readable storage mediums), memory controller  122 , one or more processing units (CPU&#39;s)  120 , peripherals interface  118 , RF circuitry  108 , audio circuitry  110 , speaker  111 , microphone  113 , input/output (I/O) subsystem  106 , other input or control devices  116 , and external port  124 . Device  100  optionally includes one or more optical sensors  164 . Device  100  optionally includes one or more intensity sensors  165  for detecting intensity of contacts on device  100  (e.g., a touch-sensitive surface such as touch-sensitive display system  112  of device  100 ). Device  100  optionally includes one or more tactile output generators  167  for generating tactile outputs on device  100  (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system  112  of device  100  or touchpad  355  of device  300 ). These components optionally communicate over one or more communication buses or signal lines  103 . 
     As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). 
     As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user&#39;s sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user&#39;s hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user&#39;s movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user. 
     It should be appreciated that device  100  is only one example of a portable multifunction device, and that device  100  optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in  FIG. 1A  are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits. 
     Memory  102  optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory  102  by other components of device  100 , such as CPU  120  and the peripherals interface  118 , is, optionally, controlled by memory controller  122 . 
     Peripherals interface  118  can be used to couple input and output peripherals of the device to CPU  120  and memory  102 . The one or more processors  120  run or execute various software programs and/or sets of instructions stored in memory  102  to perform various functions for device  100  and to process data. 
     In some embodiments, peripherals interface  118 , CPU  120 , and memory controller  122  are, optionally, implemented on a single chip, such as chip  104 . In some other embodiments, they are, optionally, implemented on separate chips. 
     RF (radio frequency) circuitry  108  receives and sends RF signals, also called electromagnetic signals.

     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data is, optionally, retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG. 2 ). The headset jack provides an interface between audio circuitry  110  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  optionally includes display controller  156 , optical sensor controller  158 , intensity sensor controller  159 , haptic feedback controller  161  and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input control devices  116  optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  160  are, optionally, coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,  208 ,  FIG. 2 ) optionally include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons optionally include a push button (e.g.,  206 ,  FIG. 2 ). 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects. 
     Touch screen  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen  112 . In an exemplary embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen  112  and display controller  156  optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  112 . In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif. 
     Touch screen  112  optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     In some embodiments, in addition to the touch screen, device  100  optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  100  optionally also includes one or more optical sensors  164 .  FIG. 1A  shows an optical sensor coupled to optical sensor controller  158  in I/O subsystem  106 . Optical sensor  164  optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor  164  receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module  143  (also called a camera module), optical sensor  164  optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  on the front of the device, so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image is, optionally, obtained for videoconferencing while the user views the other video conference participants on the touch screen display. 
     Device  100  optionally also includes one or more contact intensity sensors  165 .  FIG. 1A  shows a contact intensity sensor coupled to intensity sensor controller  159  in I/O subsystem  106 . Contact intensity sensor  165  optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor  165  receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ).

Alternately, proximity sensor  166  is coupled to input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  optionally also includes one or more tactile output generators  167 .  FIG. 1A  shows a tactile output generator coupled to haptic feedback controller  161  in I/O subsystem  106 . Tactile output generator  167  optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor  165  receives tactile feedback generation instructions from haptic feedback module  133  and generates tactile outputs on device  100  that are capable of being sensed by a user of device  100 . In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system  112 ) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device  100 ) or laterally (e.g., back and forth in the same plane as a surface of device  100 ). In some embodiments, at least one tactile output generator sensor is located on the back of device  100 , opposite touch screen display  112  which is located on the front of device  100 . 
     Device  100  optionally also includes one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 .

     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments memory  102  stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices. 
     Contact/motion module  130  optionally detects contact with touch screen  112  (in conjunction with display controller  156 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact) determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  130  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  130  and display controller  156  detect contact on a touchpad. 
     In some embodiments, contact/motion module  130  uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device  100 ). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch screen display hardware. Additionally, in some implementations a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter). 
     Contact/motion module  130  optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns and intensities. Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. 
     Graphics module  132  includes various known software components for rendering and displaying graphics on touch screen  112  or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like. 
     In some embodiments, graphics module  132  stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module  132  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  156 . 
     Haptic feedback module  133  includes various software components for generating instructions used by tactile output generator(s)  167  to produce tactile outputs at one or more locations on device  100  in response to user interactions with device  100 . 
     Text input module  134 , which is, optionally, a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing, to camera  143  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

     Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  102  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  102  optionally stores additional modules and data structures not described above. 
     In some embodiments, device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device  100 , the number of physical input control devices (such as push buttons, dials, and the like) on device  100  is, optionally, reduced. 
     The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device  100  to a main, home, or root menu from any user interface that is displayed on device  100 . In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad. 
       FIG. 1B  is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory  102  (in  FIG. 1A ) or  370  ( FIG. 3 ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripheral interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture. 
     Hit view determination module  172  receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module  172  identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view. 
     Active event recognizer determination module  173  determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module  173  determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module  173  determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views. 
     Event dispatcher module  174  dispatches the event information to an event recognizer (e.g., event recognizer  180 ). In embodiments including active event recognizer determination module  173 , event dispatcher module  174  delivers the event information to an event recognizer determined by active event recognizer determination module  173 . In some embodiments, event dispatcher module  174  stores in an event queue the event information, which is retrieved by a respective event receiver module  182 . 
     In some embodiments, operating system  126  includes event sorter  170 . Alternatively, application  136 - 1  includes event sorter  170 . In yet other embodiments, event sorter  170  is a stand-alone module, or a part of another module stored in memory  102 , such as contact/motion module  130 . 
     In some embodiments, application  136 - 1  includes a plurality of event handlers  190  and one or more application views  191 , each of which includes instructions for handling touch events that occur within a respective view of the application&#39;s user interface. Each application view  191  of the application  136 - 1  includes one or more event recognizers  180 . Typically, a respective application view  191  includes a plurality of event recognizers  180 . In other embodiments, one or more of event recognizers  180  are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application  136 - 1  inherits methods and other properties. In some embodiments, a respective event handler  190  includes one or more of: data updater  176 , object updater  177 , GUI updater  178 , and/or event data  179  received from event sorter  170 . Event handler  190  optionally utilizes or calls data updater  176 , object updater  177  or GUI updater  178  to update the application internal state  192 . Alternatively, one or more of the application views  191  includes one or more respective event handlers  190 . Also, in some embodiments, one or more of data updater  176 , object updater  177 , and GUI updater  178  are included in a respective application view  191 . 
     A respective event recognizer  180  receives event information (e.g., event data  179 ) from event sorter  170 , and identifies an event from the event information. Event recognizer  180  includes event receiver  182  and event comparator  184 . In some embodiments, event recognizer  180  also includes at least a subset of: metadata  183 , and event delivery instructions  188  (which optionally include sub-event delivery instructions). 
     Event receiver  182  receives event information from event sorter  170 . The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device. 
     Event comparator  184  compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator  184  includes event definitions  186 . Event definitions  186  contain definitions of events (e.g., predefined sequences of sub-events), for example, event  1  ( 187 - 1 ), event  2  ( 187 - 2 ), and others. In some embodiments, sub-events in an event  187  include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event  1  ( 187 - 1 ) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event  2  ( 187 - 2 ) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display  112 , and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers  190 . 
     In some embodiments, event definition  187  includes a definition of an event for a respective user-interface object. In some embodiments, event comparator  184  performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display  112 , when a touch is detected on touch-sensitive display  112 , event comparator  184  performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler  190 , the event comparator uses the result of the hit test to determine which event handler  190  should be activated. For example, event comparator  184  selects an event handler associated with the sub-event and the object triggering the hit test. 
     In some embodiments, the definition for a respective event  187  also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer&#39;s event type. 
     When a respective event recognizer  180  determines that the series of sub-events do not match any of the events in event definitions  186 , the respective event recognizer  180  enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture. 
     In some embodiments, a respective event recognizer  180  includes metadata  183  with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata  183  includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy. 
     In some embodiments, a respective event recognizer  180  activates event handler  190  associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer  180  delivers event information associated with the event to event handler  190 . Activating an event handler  190  is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer  180  throws a flag associated with the recognized event, and event handler  190  associated with the flag catches the flag and performs a predefined process. 
     In some embodiments, event delivery instructions  188  include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process. 
     In some embodiments, data updater  176  creates and updates data used in application  136 - 1 . For example, data updater  176  updates the telephone number used in contacts module  137 , or stores a video file used in video player module  145 . In some embodiments, object updater  177  creates and updates objects used in application  136 - 1 . For example, object updater  177  creates a new user-interface object or updates the position of a user-interface object. GUI updater  178  updates the GUI. For example, GUI updater  178  prepares display information and sends it to graphics module  132  for display on a touch-sensitive display. 
     In some embodiments, event handler(s)  190  includes or has access to data updater  176 , object updater  177 , and GUI updater  178 . In some embodiments, data updater  176 , object updater  177 , and GUI updater  178  are included in a single module of a respective application  136 - 1  or application view  191 . In other embodiments, they are included in two or more software modules. 
     It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices  100  with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized. 
       FIG. 2  illustrates a portable multifunction device  100  having a touch screen  112  in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or one or more styluses  203  (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device  100 . In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  optionally also includes one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  is, optionally, used to navigate to any application  136  in a set of applications that are, optionally executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In one embodiment, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , Subscriber Identity Module (SIM) card slot  210 , head set jack  212 , and docking/charging external port  124 . Push button  206  is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device  100  also accepts verbal input for activation or deactivation of some functions through microphone  113 . Device  100  also, optionally, includes one or more contact intensity sensors  165  for detecting intensity of contacts on touch screen  112  and/or one or more tactile output generators  167  for generating tactile outputs for a user of device  100 . 
       FIG. 3  is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device  300  need not be portable. In some embodiments, device  300  is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child&#39;s learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device  300  typically includes one or more processing units (CPU&#39;s)  310 , one or more network or other communications interfaces  360 , memory  370 , and one or more communication buses  320  for interconnecting these components. Communication buses  320  optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device  300  includes input/output (I/O) interface  330  comprising display  340 , which is typically a touch screen display. I/O interface  330  also optionally includes a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 , tactile output generator  357  for generating tactile outputs on device  300  (e.g., similar to tactile output generator(s)  167  described above with reference to  FIG. 1A ), sensors  359  (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s)  165  described above with reference to  FIG. 1A ). Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory  370  optionally includes one or more storage devices remotely located from CPU(s)  310 . In some embodiments, memory  370  stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory  102  of portable multifunction device  100  ( FIG. 1A ), or a subset thereof. Furthermore, memory  370  optionally stores additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  optionally stores drawing module  380 , presentation module  382 , word processing module  384 , website creation module  386 , disk authoring module  388 , and/or spreadsheet module  390 , while memory  102  of portable multifunction device  100  ( FIG. 1A ) optionally does not store these modules. 
     Each of the above identified elements in  FIG. 3  are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory  370  optionally stores a subset of the modules and data structures identified above. Furthermore, memory  370  optionally stores additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces (“UI”) that is, optionally, implemented on portable multifunction device  100 . 
       FIG. 4A  illustrates an exemplary user interface for a menu of applications on portable multifunction device  100  in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device  300 . In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator(s)  402  for wireless communication(s), such as cellular and Wi-Fi signals;   Time  404 ;   Bluetooth indicator  405 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Icon  416  for telephone module  138 , labeled “Phone,” which optionally includes an indicator  414  of the number of missed calls or voicemail messages;   Icon  418  for e-mail client module  140 , labeled “Mail,” which optionally includes an indicator  410  of the number of unread e-mails;   Icon  420  for browser module  147 , labeled “Browser;” and   Icon  422  for video and music player module  152 , also referred to as iPod (trademark of Apple Inc.) module  152 , labeled “iPod;” and   
           Icons for other applications, such as:
           Icon  424  for IM module  141 , labeled “Text;”   Icon  426  for calendar module  148 , labeled “Calendar;”   Icon  428  for image management module  144 , labeled “Photos;”   Icon  430  for camera module  143 , labeled “Camera;”   Icon  432  for online video module  155 , labeled “Online Video”   Icon  434  for stocks widget  149 - 2 , labeled “Stocks;”   Icon  436  for map module  154 , labeled “Map;”   Icon  438  for weather widget  149 - 1 , labeled “Weather;”   Icon  440  for alarm clock widget  149 - 4 , labeled “Clock;”   Icon  442  for workout support module  142 , labeled “Workout Support;”   Icon  444  for notes module  153 , labeled “Notes;” and   Icon  446  for a settings application or module, which provides access to settings for device  100  and its various applications  136 .   
               

     It should be noted that the icon labels illustrated in  FIG. 4A  are merely exemplary. For example, icon  422  for video and music player module  152  are labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon. 
       FIG. 4B  illustrates an exemplary user interface on a device (e.g., device  300 ,  FIG. 3 ) with a touch-sensitive surface  451  (e.g., a tablet or touchpad  355 ,  FIG. 3 ) that is separate from the display  450  (e.g., touch screen display  112 ). Device  300  also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors  357 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  359  for generating tactile outputs for a user of device  300 . 
     Although some of the examples which follow will be given with reference to inputs on touch screen display  112  (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in  FIG. 4B . In some embodiments the touch sensitive surface (e.g.,  451  in  FIG. 4B ) has a primary axis (e.g.,  452  in  FIG. 4B ) that corresponds to a primary axis (e.g.,  453  in  FIG. 4B ) on the display (e.g.,  450 ). In accordance with these embodiments, the device detects contacts (e.g.,  460  and  462  in  FIG. 4B ) with the touch-sensitive surface  451  at locations that correspond to respective locations on the display (e.g., in  FIG. 4B, 460  corresponds to  468  and  462  corresponds to  470 ). In this way, user inputs (e.g., contacts  460  and  462 , and movements thereof) detected by the device on the touch-sensitive surface (e.g.,  451  in  FIG. 4B ) are used by the device to manipulate the user interface on the display (e.g.,  450  in  FIG. 4B ) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein. 
     Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously. 
     As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad  355  in  FIG. 3  or touch-sensitive surface  451  in  FIG. 4B ) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system  112  in  FIG. 1A  or touch screen  112  in  FIG. 4A ) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user&#39;s intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device). 
     The user interface figures described below include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT 0 , a light press intensity threshold IT L , a deep press intensity threshold IT D , and/or one or more other intensity thresholds). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with an intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold IT 0  below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures. 
     An increase of intensity of the contact from an intensity below the light press intensity threshold IT L  to an intensity between the light press intensity threshold IT L  and the deep press intensity threshold IT D  is sometimes referred to as a “light press” input. An increase of intensity of the contact from an intensity below the deep press intensity threshold IT D  to an intensity above the deep press intensity threshold IT D  is sometimes referred to as a “deep press” input. An increase of intensity of the contact from an intensity below the contact-detection intensity threshold IT 0  to an intensity between the contact-detection intensity threshold IT 0  and the light press intensity threshold IT L  is sometimes referred to as detecting the contact on the touch-surface. A decrease of intensity of the contact from an intensity above the contact-detection intensity threshold IT 0  to an intensity below the contact intensity threshold IT 0  is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT 0  is zero. In some embodiments IT 0  is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact. 
     In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input). 
     In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90% or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances). 
     For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold. 
     User Interfaces and Associated Processes 
     Manipulating Framed Graphical Objects 
     Many electronic devices have graphical user interfaces that include various graphical objects and frames that are controlled by a confusing set of overlapping and sometimes conflicting inputs. For example, photo album software allows a user to arrange and customize pictures to be displayed or printed at a later time. In this example, customizing the pictures may include selecting which frame to put a picture in and adjusting the picture&#39;s appearance within the frame. There is a need to provide a fast, efficient, and convenient way for users to manipulate the pictures (or other graphical objects) inside, outside, and between frames. The embodiments described below provide a fast, efficient, and convenient way for users to manipulate the graphical objects inside, outside, and between frames using inputs that are differentiated in accordance with an intensity of the inputs. 
       FIGS. 5A-5F  illustrate exemplary user interfaces for manipulating framed graphical objects using gestures on a touch-sensitive surface in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes described below with reference to  FIGS. 6A-6B .  FIGS. 5C-5F  include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a respective threshold (e.g., “IT D ”). In some embodiments, operations similar to those described below with reference to IT D  are performed with reference to a different intensity threshold (e.g., “IT L ”). 
       FIG. 5A  illustrates an example of a user interface that includes a framed graphical object. User interface  800  is displayed on display  450  of a device (e.g., device  300 ) and is responsive to gestures on touch-sensitive surface  451 . User interface  800  includes graphical object  802  displayed within frame  804 . 
     In some embodiments, the device is an electronic device with a separate display (e.g., display  450 ) and a separate touch-sensitive surface (e.g., touch-sensitive surface  451 ). In some embodiments, the device is portable multifunction device  100 , the display is touch-sensitive display system  112 , and the touch-sensitive surface includes tactile output generators  167  on the display ( FIG. 1A ). For convenience of explanation, the embodiments described with reference to  FIGS. 5A-5F and 6A-6B  will be discussed with reference to display  450  and a separate touch-sensitive surface  451 , however analogous operations are, optionally, performed on a device with a touch-sensitive display system  112  in response to detecting the contacts described in  FIGS. 5A-5F  on the touch-sensitive display system  112  while displaying the user interfaces shown in  FIGS. 5A-5F  on the touch-sensitive display system  112 ; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 , in place of cursor  806   
       FIG. 5B  illustrates another example of a user interface. In  FIG. 5B , user interface  800  includes a plurality of frames  804 - 1  through  804 - 3  and a plurality of graphical objects  802 - 1  through  802 - 2 . Per some embodiments, graphical user interface  800  in  FIG. 5B  also includes a displayed representation of focus selector  806  (e.g., a cursor), responsive to gestures on touch-sensitive surface  451 . As shown in  FIG. 5B , a frame may be empty (e.g., frame  804 - 2 ). Alternatively, a frame may contain one or more graphical objects (e.g., frame  804 - 1  contains graphical object  802 - 1  such as a picture or chart). In the examples described below with reference to  FIGS. 5A-5F , the graphical objects  802  are pictures, and there is no more than one graphical object in a respective frame  804  at a time. However, in some embodiments, multiple graphical objects can be placed in a single frame (e.g., multiple shapes or icons on a canvas of a drawing application), and the multiple graphical objects are configured to be moved/resized relative to each other within the frame and moved in and out of respective frames independently of each other. 
     In some implementations, a displayed representation of focus selector  806  is a cursor with a position on display  450  that is determined in accordance with contacts received by touch-sensitive surface  451 . In other implementations the focus selector has a different displayed representation (e.g., a magnifying glass). Alternatively, in some implementations a representation of the focus selector is not displayed. For example, in implementations using a touch-sensitive display system, the position of the focus selector corresponds to the location on the display of a contact or gesture. Further, the focus selector is herein defined to be “over” a user interface object when the position of the focus selector corresponds to the location on the display of the user interface object. 
       FIG. 5C  illustrates an example of removing a graphical object from a frame. In this example, graphical object  802 - 1  is initially within frame  804 - 1 , as shown in  FIG. 5B . In response to detecting a gesture, graphical object  802 - 1  is removed from frame  804 - 1  in accordance with a determination that contact  808  on the touch-sensitive surface meets predefined intensity criteria (with the intensity represented by a dense patterned background in contact  808  and the intensity meter showing that the intensity of contact  808  is above a respective intensity threshold IT D ). In some embodiments, as shown in  FIG. 8C , an icon or thumbnail image  812  of the graphical object is displayed at or near a location of the focus selector (e.g., cursor  806 ) in response to detecting the increase in intensity of contact  808  (e.g., in conjunction with or after ceasing to display the graphical object from the frame).  FIGS. 5C-5D  further illustrate movement  810  of the contact on the touch-sensitive surface  451  that corresponds to movement of focus selector  806  outside of frame  804 - 1 . In some embodiments, thumbnail image  812  of the graphical object moves in accordance with movement of focus selector  806 . 
     As shown in  FIG. 5C , a user gesture on touch-sensitive surface  451  includes contact  808  while focus selector  806  is over a graphical object  802  and movement  810  of the contact across touch-sensitive surface  451 . In some embodiments, the predetermined intensity criteria include that the contact reaches an intensity during the gesture above a respective intensity threshold at any point in time during the gesture. In some embodiments, the predefined intensity criteria include that the contact reaches an intensity during the gesture above a respective intensity threshold before the focus selector moves outside of the frame. In some embodiments, the predefined intensity criteria include that the contact reaches an intensity during the gesture above a respective intensity threshold prior to detecting the movement of the contact. 
     In some embodiments, the graphical object is removed from the frame in response to detecting the increase in intensity of the contact to an intensity that is greater than a respective intensity threshold (e.g., IT D ). In some embodiments, after the graphical object has been removed from the frame, the graphical object continues to be removed from the frame even if the intensity of the contact decreases below the respective intensity threshold (e.g., IT D ). For example, after the graphical object has been picked up/selected the selection of the graphical object is maintained (e.g., a representation of the graphical object is not dropped and the graphical object is not returned to the frame) when the intensity of the contact decreases to an intensity below IT D , and the graphical object is dropped in a different frame and/or returned to the frame when the intensity of the contact is reduced below IT L . As another example, after the graphical object has been picked up/selected the selection of the graphical object is maintained (e.g., a representation of the graphical object is not dropped and the graphical object is not returned to the frame) when the intensity of the contact decreases to an intensity below IT D , and the graphical object is dropped in a different frame and/or returned to the frame when the contact is lifted off of the touch-sensitive surface (e.g., the intensity of the contact is reduced below IT 0 ). Thus, in some embodiments, in response to detecting a press input on the touch-sensitive surface that includes a contact with an intensity above IT D , the device enters an object-movement mode in which the graphical object that was in the frame is moved to a location corresponding to a focus selector (e.g., a frame or portion of a user interface over which the focus selector is located) when the device exits the object-movement mode without regard to whether or not the intensity of the contact was above IT D  while the device was in the object-movement mode. In some embodiments, the device exits the object-movement mode in response to detecting a decrease in intensity of the contact below a different intensity threshold (e.g., IT L ) such as IT L . In some embodiments, the device exits the object-movement mode in response to detecting liftoff of the contact from the touch-sensitive surface (e.g., a decrease in intensity of the contact below IT 0 ). In some embodiments, the device exits the object-movement mode in response to detecting an increase in intensity of the contact from an intensity below a different intensity threshold (e.g., IT L ) to an intensity above the respective intensity threshold (e.g. IT D ). 
       FIGS. 5B and 5D  illustrate an example of moving a graphical object from one frame to another frame. In this example, graphical object  802 - 1  is initially within frame  804 - 1 , as shown in  FIG. 5B . In response to detecting a gesture, graphical object  802 - 1  is removed from frame  804 - 1  in accordance with a determination that contact  808  meets the predefined intensity criteria (with the intensity represented by a dense patterned background in contact  808 ).  FIG. 5D  further illustrates the contact having an initial position  808 - a  and movement of the contact  810  to a final position  808 - b  on the touch-sensitive surface. In response to detecting an end of the gesture (e.g., liftoff of contact  808  from the touch-sensitive surface  451 ) at contact position  808 - b , graphical object  802 - 1  is moved to frame  804 - 2 . In some embodiments, graphical object  802 - 1  is moved to frame  804 - 2  in response to detecting liftoff contact  808 - b . In some embodiments, graphical object  802 - 1  is moved to frame  804 - 2  in response to detecting a reduction in intensity of contact  808 - b  to an intensity below IT L . 
       FIGS. 5B and 5E  illustrate an example of adjusting the appearance of a graphical object within a frame. The appearance of graphical object  802 - 1  is adjusted inside of frame  804 - 1 , in accordance with a determination that the contact does not meet the predefined intensity criteria (with the intensity represented by a sparse patterned background in contact  808  and the intensity meter showing that the intensity of contact  814  is above a respective intensity threshold IT D ). Graphical object  802 - 1  has an initial appearance in frame  804 - 1  as shown in  FIG. 5B  and, in this example, adjusting the appearance of graphical object  802 - 1  includes translating it laterally within frame  804 - 1  (e.g., moving the graphical object vertically, horizontally, or diagonally within the frame). Although focus selector  806  moves outside of frame  804 - 1 , graphical object  802 - 1  is not removed from frame  804 - 1  because the contact intensity does not exceed the respective intensity threshold (e.g., “IT D ” in  FIG. 5E ). 
       FIGS. 5B and 5F  also illustrate an example of adjusting the appearance of a graphical object within a frame, rather than removing the graphical object from the frame. The appearance of graphical object  802 - 1  is adjusted inside of frame  804 - 1 , in accordance with a determination that contacts  818  and  822  do not meet the predefined intensity criteria (represented by a sparse patterned background in contacts  818  and  822  and the intensity meters for the respective contacts that show that the respective intensities of the respective contacts are below the respective intensity threshold IT D  and above intensity threshold IT L ).  FIG. 5F  further illustrates detecting a gesture that includes a plurality of contacts  818  and  822  and the respective movement  820  and  824  of the contacts. Graphical object  802 - 1  has an initial appearance in frame  804 - 1  as shown in  FIG. 5B  and, in this example, adjusting the appearance of graphical object  802 - 1  in accordance with the movement of the plurality of contacts  818  and  822 , includes resizing graphical object  802 - 1  within frame  804 - 1 . 
       FIGS. 6A-6B  are flow diagrams illustrating a method  900  of manipulating framed graphical objects in accordance with some embodiments. The method  900  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  900  are, optionally, combined and/or the order of some operations are, optionally, changed. 
     As described below, the method  900  provides an intuitive way to manipulate framed graphical objects. The method reduces the cognitive burden on a user when manipulating a framed graphical object, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to manipulate framed graphical objects faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 902 ) a graphical object inside of a frame on the display.  FIG. 5A , for example, shows graphical object  802  and frame  804 , displayed in graphical user interface  800 . 
     The device detects ( 904 ) a gesture that includes detecting ( 906 ) a contact on the touch-sensitive surface while a focus selector is over the graphical object and detecting ( 908 ) movement of the contact across the touch-sensitive surface. Thus, in some embodiments, the gesture includes detecting a contact on the touch-sensitive surface and then detecting subsequent movement of the contact on the touch-sensitive surface. As shown in  FIG. 5C , for example, contact  808  and movement  810  of the contact is detected on touch-sensitive surface  451 . In some embodiments, movement of the contact corresponds to movement of the focus selector outside of the frame ( 910 ). In  FIGS. 5C-5E , for example, focus selector  806  moves outside of frame  804 - 1  during movement  810  of the contact on touch-sensitive surface  451 . 
     In response to detecting the gesture ( 912 ), in accordance with a determination that the contact meets predefined intensity criteria ( 914 ), the device removes the graphical object from the frame ( 916 ). For example,  FIG. 5C  shows contact  808  having an intensity above the respective intensity threshold (e.g., “IT D ”), and removing graphical object  802 - 1  from frame  804 - 1 . In some embodiments, after removing the graphical object from the frame, the device continues to detect movement of the contact, where the movement of the contact corresponds to movement of the focus selector, and the device displays a thumbnail image of the graphical object moving on the display in accordance with movement of the focus selector ( 918 ). For example,  FIG. 5C  shows frame  804 - 1  as being empty (graphical object  802 - 1  has been removed) and thumbnail  812  moving in accordance with movement of focus selector  806 . 
     Conversely, in response to detecting the gesture ( 912 ), in accordance with a determination that the contact does not meet ( 922 ) the predefined intensity criteria (e.g., the contact had a maximum intensity during the gesture below the respective intensity threshold), the device adjusts ( 924 ) the appearance of the graphical object inside of the frame. For example  FIG. 5E  shows a gesture that includes contact  814  and movement  816  of the contact from 814-a to  814 - b , contact  814  having an intensity below the respective intensity threshold (e.g., contact with intensity below IT D  and, optionally, above IT L ). For example  FIG. 5F  shows a depinch gesture that includes contacts  818  and  822  with movements  820  and  824 , respectively, with contacts  818  and  822  having intensities below the respective intensity threshold (e.g., contacts with intensities below IT D  and, optionally, above IT L ). The appearance of graphical object  802 - 1  is adjusted within frame  804 - 1  in both examples in response to detecting the respective gestures, rather than removing graphical object  802 - 1  from the frame. In some embodiments, in response to detecting a gesture with a contact having an intensity below a lower intensity threshold (e.g., “IT L ”) while the focus selector is over frame  804 - 1 , the device moves the focus selector away from frame  804 - 1  without adjusting the appearance of graphical object  802 - 1  within the frame and without removing the graphical object  802 - 1  from frame  804 - 1  (e.g., without moving graphical object  802 - 1  to a different frame). 
     In some embodiments, adjusting the appearance of the graphical object inside of the frame includes translating the graphical object laterally within the frame ( 925 ). FIG.  5 E, for example, shows graphical object  802 - 1  shifted (translated laterally) within frame  804 - 1 . In some embodiments, adjusting the appearance of the graphical object inside of the frame includes resizing the graphical object within the frame ( 926 ). For example,  FIG. 5F  shows graphical object  802 - 1  enlarged (resized) within frame  804 - 1 . 
     In some embodiments, the predefined intensity criteria include that ( 928 ) the contact reached an intensity during the gesture above a respective intensity threshold before the focus selector moved outside of the frame. In these embodiments, in  FIG. 5D , contact  808  reaches an intensity above the respective intensity threshold before the focus selector  806  moved outside of frame  804 - 1  in accordance with movement  810  of the contact on the touch-sensitive surface. 
     In some embodiments, the predefined intensity criteria include that ( 930 ) the contact reached an intensity during the gesture above a respective intensity threshold (e.g., “IT D ”) at any point in time during the gesture (e.g., before or after the focus selector moves outside of the frame). In these embodiments, in  FIG. 5D , contact  808  reached an intensity above the respective intensity at any point in time during movement of the contact through the end of the gesture at position  808 - b.    
     In some embodiments, the predefined intensity criteria include that ( 932 ) the contact reached an intensity during the gesture above a respective intensity threshold (e.g., “IT D ”) prior to detecting the movement of the contact. Thus, in some embodiments, the mode of interacting with the graphical object (e.g., constrained-within-frame or unconstrained) is determined before the contact starts to move. In these embodiments, in  FIG. 5D , contact  808  reached an intensity above the respective intensity threshold at initial position  808 - a  before movement  810  of the contact. 
     In some embodiments, after the graphical object has been removed from the frame, the device detects ( 934 ) an end of the gesture (e.g., liftoff of contact  808  from the touch-sensitive surface), and in response to detecting the end of the gesture, the device moves ( 936 ) the graphical object to a different frame. For example, in  FIG. 5D  an end of the gesture made with contact  808  is detected and graphical object  802 - 1  is displayed within frame  804 - 2 . 
     It should be understood that the particular order in which the operations in  FIGS. 6A-6B  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method  900  described above with respect to  FIGS. 6A-6B . For example, the gestures, contacts, intensity thresholds, graphical objects, frames, focus selectors, and thumbnails described above with reference to method  900  may have one or more of the characteristics of the gestures, contacts, intensity thresholds, graphical objects, frames, focus selectors, and thumbnails described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here. 
     In accordance with some embodiments,  FIG. 7  shows a functional block diagram of an electronic device  1000  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 7  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. As shown in  FIG. 7 , an electronic device  1000  includes a display unit  1002  configured to display a graphical object inside of a frame; a touch-sensitive surface unit  1004  configured to receive user gestures; one or more sensor units  1005  configured to detect intensity of contacts with the touch-sensitive surface unit; and a processing unit  1006  coupled to the display unit  1002 , the touch-sensitive surface unit  1004 , and the sensor units  1005 . In some embodiments, the processing unit includes a detecting unit  1008 , a display enabling unit  1010 , a moving unit  1012 , and an adjusting unit  1014 . 
     The processing unit  1006  is configured to: detect a gesture (e.g., with the detecting unit  1008 ), wherein detecting the gesture includes: detecting a contact on the touch-sensitive surface unit  1004  while a focus selector is over the graphical object; and detecting movement of the contact across the touch-sensitive surface unit  1004 ; and in response to detecting the gesture: in accordance with a determination that the contact met predefined intensity criteria, remove the graphical object from the frame (e.g., with the moving unit  1012 ); and in accordance with a determination that the contact did not meet the predefined intensity criteria, adjust an appearance of the graphical object inside of the frame (e.g., with the adjusting unit  1014 ). 
     In some embodiments, the movement of the contact corresponds to movement of the focus selector outside of the frame. 
     In some embodiments, the predefined intensity criteria include that the contact reached an intensity during the gesture above a respective intensity threshold before the focus selector moved outside of the frame. 
     In some embodiments, the predefined intensity criteria include that the contact reached an intensity during the gesture above a respective intensity threshold at any point in time during the gesture. 
     In some embodiments, the predefined intensity criteria include that the contact reached an intensity during the gesture above a respective intensity threshold prior to detecting the movement of the contact. 
     In some embodiments, adjusting the appearance of the graphical object inside of the frame (e.g., with the adjusting unit  1014 ) includes translating the graphical object laterally within the frame on the display unit  1002 . 
     In some embodiments, adjusting the appearance of the graphical object inside of the frame (e.g., with the adjusting unit  1014 ) includes resizing the graphical object within the frame on the display unit  1002 . 
     In some embodiments, the processing unit  1006  is further configured to continue to detect movement of the contact (e.g., with the detecting unit  1008 ), wherein the movement of the contact corresponds to movement of the focus selector; and enable display of (e.g., with the display enabling unit  1010 ) a thumbnail image of the graphical object moving on the display unit  1002  in accordance with movement of the focus selector after removing the graphical object from the frame. 
     In some embodiments, the processing unit  1006  is further configured to detect an end of the gesture; and respond to detecting the end of the gesture by moving (e.g., with the moving unit  1012 ) the graphical object to a different frame on the display unit  1002 . 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 6A-6B  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 7 . For example, detection operation  906 , removing operation  916 , adjusting operation  924  and moving operation  936  are, optionally implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally utilizes or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
     Manipulating Images and Masked Images 
     Many electronic devices have graphical user interfaces that include various masked images that are controlled by a confusing set of overlapping and sometimes conflicting inputs. For example, masking an image is often useful when preparing a document for presentation. In this example, a user will often want to display only part of a larger image or the user will want to adjust the orientation of the image for presentation. Utilizing image masks allows the user to perform these tasks without modifying the original image. However modifying an image mask or an original image that is masked by the image mask sometimes requires multiple steps including navigating through multiple menus to locate controls for modifying the image mask or the original image. There is often a need to provide a fast, efficient, and convenient way for users to transition between modifying the masked image (the image mask and the original image concurrently) and modifying the original image corresponding to the masked image. The embodiments described below provide a fast, efficient, and convenient way for users to transition between modifying the masked image (the image mask and the original image concurrently) and modifying the original image corresponding to the masked image using inputs that are differentiated in accordance with an intensity of the inputs. 
       FIGS. 8A-8N  illustrate exemplary user interfaces for manipulating images and masked images using gestures on a touch-sensitive surface in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below with reference to  FIGS. 9A-9C .  FIGS. 8A-8N  include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a respective threshold (e.g., “IT D ”). In some embodiments, operations similar to those described below with reference to IT D  are performed with reference to a different intensity threshold (e.g., “IT L ”). 
       FIG. 8A  illustrates an example of a user interface that includes a masked image. User interface  1500  is displayed on display  450  of a device (e.g., device  300 ) and is responsive to gestures on touch-sensitive surface  451 . User interface  1500  includes masked image  1502  displayed within image mask  1504 . 
     In some embodiments, the device is an electronic device with a separate display (e.g., display  450 ) and a separate touch-sensitive surface (e.g., touch-sensitive surface  451 ). In some embodiments, the device is portable multifunction device  100 , the display is touch-sensitive display system  112 , and the touch-sensitive surface includes tactile output generators  167  on the display ( FIG. 1A ). For convenience of explanation, the embodiments described with reference to  FIGS. 8A-8N and 9A-9C  will be discussed with reference to display  450  and a separate touch-sensitive surface  451 , however analogous operations are, optionally, performed on a device with a touch-sensitive display system  112  in response to detecting the contacts described in  FIGS. 8A-8N  on the touch-sensitive display system  112  while displaying the user interfaces shown in  FIGS. 8A-8N  on the touch-sensitive display system  112 ; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 , in place of cursor  1506 . 
       FIG. 8B  illustrates another example of a user interface. In  FIG. 8B , user interface  1500  includes masked image  1502  displayed within image mask  1504 . In this example, masked image  1502  is displayed within electronic document  1508  on user interface  1500 , per some embodiments. In some embodiments, graphical user interface  1500  in  FIG. 8B  also includes a displayed representation of focus selector  1506 , which is displayed on a portion of the user interface that does not include masked image  1502 . Focus selector  1506  is responsive to gestures on touch-sensitive surface  451 . For example, in  FIG. 8B , the device detects movement of contact  1510  down and to the right on the touch-sensitive surface  451  while an intensity of contact  1510  is between a contact-detection intensity threshold (e.g., “IT 0 ”) and a light press intensity threshold (e.g., “IT L ”) and in response to detecting the movement of contact  1510 , focus selector  1506  is moved down and to the right on display  450  to a position on the display  450  that is over masked image  1502  (e.g., as shown in  FIG. 8C ). 
     In some embodiments, a displayed representation of focus selector  1506  is a cursor with a position on display  450  in accordance with contacts received by touch-sensitive surface  451 . In other embodiments the focus selector has a different displayed representation (e.g., a magnifying glass). Alternatively, in some embodiments a representation of the focus selector is not displayed. For example, in embodiments using a touch-sensitive display system, the position of the focus selector corresponds to the location on the display of a contact or gesture. Further, the focus selector is herein defined to be “over” a user interface object when the position of the focus selector corresponds to the location on the display of the user interface object. It should be appreciated that the focus selector can be any component of an electronic device that determines the position of a gesture within a user interface. 
       FIGS. 8C-8D  illustrate an example of modifying a masked image. In this example, masked image  1502  is displayed at an initial position  1502 - a  within electronic document  1508 , as shown in  FIG. 8C . In  FIG. 8D , masked image  1502  has been moved to position  1502 - b . The movement of masked image  1502  from initial position  1502 - a  to position  1502 - b  corresponds to movement of focus selector  1506  in accordance with movement  1512  of the contact  1510  on touch-sensitive surface  451 . In some embodiments,  FIGS. 8C-8D  further illustrate displaying a current selection indicator that indicates a user interface object that will be adjusted in accordance with the gesture. In this instance, current selection indicator  1514  comprises handles (eight graphical dots) around the border of masked image  1502 . In this example, contact  1510 , corresponding to focus selector  1506 , has a maximum intensity below a respective intensity threshold (e.g., “IT D ”). 
     As shown in  FIG. 8D , a user gesture on touch-sensitive surface  451  includes contact  1510  while focus selector  1506  is over masked image  1502  and movement  1512  of the contact across touch-sensitive surface  451 , and in response to detecting the gesture, the device moves masked image  1502  up and to the right on display  450 , as shown in  FIG. 8D . 
       FIGS. 8E-8F  illustrate an example of modifying an original image corresponding to a masked image relative to an image mask. In this example, contact  1510  has a maximum intensity that is above a respective intensity threshold (e.g., “IT D ”). Original image  1516 , corresponding to masked image  1502 , is revealed at initial position  1516 - a , as shown in  FIG. 8E . The movement of original image  1516  from initial position  1516 - a  to position  1516 - b  (as shown in  FIG. 8F ) corresponds to movement of focus selector  1506  in accordance with movement  1513  of contact  1510  on touch-sensitive surface  451 .  FIGS. 8E-8F  further illustrate an example of current selection indicator  1514  comprising handles (eight graphical dots) around the border of original image  1516  indicating that original image  1516  will be adjusted in accordance with the gesture. As shown in  FIG. 8F , image mask  1504  is not moved by the user gesture in this example because contact  1510  has a maximum intensity that is above the respective intensity threshold. Therefore, only original image  1516  is moved. 
     In some embodiments, the original image (e.g., image  1516 - a  in  FIG. 8E ) is displayed along with image mask (e.g., image mask  1504  in  FIG. 8E ) in response to detecting the increase in intensity of the contact to an intensity that is greater than a respective intensity threshold (e.g., IT D ), as shown in  FIG. 8E . In some embodiments, after the original image and image mask have been displayed, the original image and image mask continue to be displayed even if the intensity of the contact decreases below the respective intensity threshold (e.g., IT D ). For example, after the original image and image mask have been displayed, the display of the original image and image mask is maintained when the intensity of the contact decreases to an intensity below IT D , and the original image and image mask are replaced with a masked image when the intensity of the contact is reduced below IT L . As another example, after the original image and image mask the display of the original image and image mask is maintained when the intensity of the contact decreases to an intensity below IT D , and the original image and image mask are replaced with a masked image when the contact is lifted off of the touch-sensitive surface (e.g., the intensity of the contact is reduced below IT 0 ). Thus, in some embodiments, in response to detecting a press input on the touch-sensitive surface that includes a contact with an intensity above IT D , the device enters an mask-edit mode in which the image mask and the original image can be modified (e.g., moved and/or resized) independently of each other without regard to whether or not the intensity of the contact is above IT D . In some embodiments, the device exits the mask-edit mode in response to detecting a decrease in intensity of the contact below a different intensity threshold (e.g., IT L ) such as IT L . In some embodiments, the device exits the mask-edit mode in response to detecting liftoff of the contact from the touch-sensitive surface (e.g., a decrease in intensity of the contact below IT 0 ). In some embodiments, the device exits the mask-edit mode in response to detecting an increase in intensity of the contact from an intensity below a different intensity threshold (e.g., IT L ) to an intensity above the respective intensity threshold (e.g. IT D ). In some embodiments, original image  1516 - a  is moved relative to image mask  1504  while contact has an intensity between IT L  and IT D  (e.g., contact  1510  has an intensity between IT L  and IT D  during some or all of movement  1513 ). In some embodiments, original image  1516 - a  is moved relative to image mask  1504  while contact has an intensity between IT 0  and IT D  (e.g., contact  1510  has an intensity between IT 0  and IT L  during some or all of movement  1513 ). 
       FIGS. 8G-8H  illustrate another example of modifying a masked image. In this example, the gesture includes a plurality of contacts  1515  and movement  1517  of the plurality of contacts relative to each other on touch-sensitive surface  451 , as shown in  FIG. 8H .  FIG. 8G  shows the initial size of masked image  1502  and  FIG. 8H  shows masked image  1502  reduced in size in accordance with movement  1517  of contacts  1515  on touch-sensitive surface  451 . 
       FIGS. 8I-8J  illustrate another example of modifying an original image corresponding to a masked image within an image mask. In this example, the gesture again includes a plurality of contacts  1515  and movement  1517  of the plurality of contacts relative to each other on touch-sensitive surface  451 , as shown in  FIG. 8J . In response to detecting the gesture and in accordance with a determination that contacts  1515  have a maximum intensity that is above a respective intensity threshold (e.g., “IT D ”) during the gesture, original image  1516  is resized without resizing image mask  1504 .  FIG. 8I  shows the initial size of original image  1516  and  FIG. 8J  shows original image  1516  reduced in size in accordance with movement  1517  of contacts  1515  on touch-sensitive surface  451 . 
       FIGS. 8K-8N  illustrate an example of adjusting the appearance of a current selection indicator, for example in response to determining that a contact (e.g., contact  1515 - 1  or contact  1515 - 2  in  FIG. 8K ) has exceeded a respective intensity threshold (e.g., “IT D ”). In this example, current selection indicator  1514  comprises handles (eight graphical dots) around the border of a selected user interface object as illustrated in  FIG. 8K .  FIG. 8K  shows an initial state of current selection indicator  1514  at initial position  1514 - a  indicating that masked image  1502  will be adjusted, while contacts  1515  have an intensity below the respective intensity threshold. In  FIG. 8L , after detecting an increase in intensity of contacts  1515  above the respective intensity threshold (e.g., “IT D ”) original image  1516  is revealed and continuous animation of current selection indicator  1514  occurs. In this instance, continuous animation of current selection indicator  1514  includes the handles moving from an initial position (e.g., position  1514 - a  in  FIG. 8L ) indicating that masked image  1502  will be adjusted to intermediate positions (e.g., position  1514 - b  in  FIG. 8M ) to an end position (e.g., position  1514 - c  in  FIG. 8N ) indicating that original image  1516  will be adjusted. 
       FIGS. 9A-9C  are flow diagrams illustrating a method  1600  of manipulating images and masked images in accordance with some embodiments. The method  1600  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  1600  are, optionally, combined and/or the order of some operations may be changed. 
     As described below, the method  1600  provides an intuitive way to manipulate images and masked images. The method reduces the cognitive burden on a user when manipulating images and masked images, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to manipulate images and masked images faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 1602 ) a masked image, where the masked image corresponds to an original image that is at least partially hidden in accordance with a corresponding image mask. In some embodiments, the masked imaged is displayed in an electronic document.  FIG. 8E , for example, shows masked image  1502  relative to image mask  1504  and corresponding to original image  1516 . 
     The device detects ( 1604 ) a gesture that includes a contact ( 1606 ) on the touch-sensitive surface (e.g., a finger contact) while a focus selector is over the graphical object and movement ( 1608 ) of the contact across the touch-sensitive surface. As shown in  FIG. 8D , for example, contact  1510  and movement  1512  of the contact is detected on touch-sensitive surface  451 . In some embodiments, the gesture includes lateral movement of the contact across the touch-sensitive surface. In some embodiments, the gesture includes a plurality of contacts and movement of the plurality of contacts relative to each other on the touch-sensitive surface. 
     In response to detecting a gesture ( 1610 ) one or more of operations  1612 - 1622  are performed. In accordance with a determination that the contact has a maximum intensity that is below a respective intensity threshold (e.g., “IT D ”) during the gesture, the device modifies ( 1612 ) the masked image in accordance with the gesture; where modifying the masked image includes concurrently modifying the image mask and the original image. For example,  FIGS. 8C-8D  show contact  1510  having a maximum intensity that is below a respective intensity threshold (e.g., “IT D ”). Therefore, masked image  1502  is modified (moved from position  1502 - a  in  FIG. 8C  to position  1502 - b  in  FIG. 8D ). 
     In response to detecting a gesture and in accordance with a determination that the contact reaches an intensity during the gesture that is above the respective intensity threshold, the device adjusts ( 1614 ) the original image (e.g., by resizing, rotating and/or repositioning the original image) relative to the image mask in accordance with the gesture. In some embodiments, the determination as to whether to modify the masked image or to modify the original image inside of the image mask is made based on an intensity of the contact before movement of the contact is detected. For example,  FIGS. 8E-8F  show contact  1510  having a maximum intensity that is above a respective intensity threshold (represented by a dense patterned background in contact  1510 ). Therefore, as shown in  FIG. 8F  original image  1516  is modified (moved from position  1516 - a  in  FIG. 8E  to position  1516 - b  in  FIG. 8F ) without adjusting or modifying image mask  1504 . 
     In some embodiments, adjusting the original image relative to the image mask in accordance with the gesture includes adjusting ( 1616 ) the original image without modifying the image mask. Thus, in some embodiments, in some embodiments, when the contact has an intensity above the respective intensity threshold, the original image is adjusted independently from the image mask.  FIGS. 8E-8F , for example, illustrate original image  1516  moving from position  1516 - a  ( FIG. 8E ) to position  1516 - b  ( FIG. 8F ) in accordance with movement of focus selector  1506  and without modification to image mask  1504 . 
     In some embodiments, the masked image is displayed in an electronic document, the gesture includes lateral movement of the contact across the touch-sensitive surface, modifying the masked image in accordance with the gesture includes repositioning ( 1618 ) the masked image within the electronic document in accordance with the lateral movement of the contact on the touch-sensitive surface, and adjusting the original image relative to the image mask in accordance with the gesture includes repositioning the original image relative to the image mask in accordance with the lateral movement of the contact on the touch-sensitive surface, without moving the image mask within the electronic document. As a result, when the contact has an intensity below the respective intensity threshold the whole masked image is repositioned in response to detecting the gesture, whereas when the contact has an intensity above the respective intensity threshold, a different portion of the original image is shown inside the image mask in response to detecting the gesture. In  FIGS. 8C-8D , for example, masked image  1502  is displayed within electronic document  1508  and is moved from position  1502 - a  ( FIG. 8C ) to position  1502 - b  ( FIG. 8D ) in accordance with lateral movement  1512  of contact  1510  on touch-sensitive surface  451 . In contrast, in  FIGS. 8E-8F , for example, original image  1516  is displayed (corresponding to masked image  1502  within electronic document  1508 ) and is moved from position  1516 - a  ( FIG. 8E ) to position  1516 - b  ( FIG. 8F ) in accordance with lateral movement  1513  of contact  1510  on touch-sensitive surface  451 . Image mask  1504  is not moved in  FIGS. 8E-8F  in accordance with a determination that contact  1510  reaches an intensity during the gesture that is above the respective intensity threshold. 
     In some embodiments, the aforementioned masked image is displayed in an electronic document, the gesture includes a plurality of contacts and movement of the plurality of contacts relative to each other on the touch-sensitive surface, modifying the masked image in accordance with the gesture includes resizing ( 1620 ) the masked image within the electronic document in accordance with the movement of the plurality of contacts relative to each other on the touch-sensitive surface, and adjusting the original image relative to the image mask in accordance with the gesture includes resizing the original image relative to the image mask in accordance with the movement of the plurality of contacts relative to each other on the touch-sensitive surface, without resizing the image mask within the electronic document. As a result, when the contact has an intensity below the respective intensity threshold the whole masked image is resized in response to detecting the gesture, whereas when the contact has an intensity above the respective intensity threshold, the original image resized without resizing the mask in response to detecting the gesture. In  FIGS. 8G-8H , for example, masked image  1502  is resized within electronic document  1508 .  FIG. 8G  shows the initial size of masked image  1502  and  FIG. 8H  shows masked image  1502  reduced in size in accordance with movement  1517  of contacts  1515  on touch-sensitive surface  451 . In contrast, in  FIGS. 8I-8J , for example, original image  1516  is resized within electronic document  1508 .  FIG. 8I  shows the initial size of original image  1516  and  FIG. 8J  shows original image  1516  reduced in size in accordance with movement  1517  of contacts  1515  on touch-sensitive surface  451 . Image mask  1504  is not resized in  FIGS. 8I-8J  in accordance with a determination that a contact  1515  reaches an intensity during the gesture that is above the respective intensity threshold. 
     In some embodiments, prior to detecting the gesture, the device operates in a masked-image-manipulation mode in which the mask and the original image are modified together, and in response to detecting that the contact has an intensity over the respective intensity threshold, the device enters and subsequently operates in ( 1622 ) a mask-edit mode where the mask and the original image can be modified (e.g., moved and/or resized) independently of each other. In  FIGS. 8C-8D , for example, masked image  1502  and image mask  1504  are moved (modified) together, corresponding to a device operating in a masked-image-manipulation mode. In contrast, in  FIGS. 8E-8F , for example, contact  1510  has an intensity over the respective intensity threshold and original image  1516  is moved (modified) independent of image mask  1504 , corresponding to the device operating in a mask-edit mode. 
     In some embodiments, the device displays ( 1624 ) a current selection indicator that indicates a user interface object that will be adjusted in accordance with the gesture. In  FIG. 8C , for example, current selection indicator  1514  is displayed indicating that masked image  1502  will be adjusted in accordance with the gesture. In this example, current selection indicator  1514  comprises handles (eight graphical dots) around the border of masked image  1502 . 
     In some embodiments, while the contact has an intensity below the respective intensity threshold, the current selection indicator indicates that the masked image will be adjusted in accordance the gesture ( 1626 ). In some of these embodiments, the device detects ( 1628 ) an increase in intensity of the contact above the respective intensity threshold, and in response to detecting the increase in intensity of the contact above the respective intensity threshold, the device adjusts ( 1630 ) the appearance of the current selection indicator to indicate that the original image will be adjusted (e.g., without adjusting the image mask) in accordance with the gesture. For example, in  FIGS. 8K-8N , current selection indicator  1514  initially indicates that masked image  1502  will be adjusted ( FIG. 8K ) and in response to determining that a respective contact (e.g.,  1515 - 1  or  1515 - 2 ) has exceeded the respective intensity threshold, current selection indicator  1514  indicates that original image  1516  will be adjusted ( FIG. 8N ). 
     In some embodiments, adjusting the appearance of the current selection indicator includes displaying a continuous animation of a set of resizing handles moving from an a first boundary indicating an extent of the masked image on the display to a second boundary indicating an extent of the original image on the display ( 1632 ).  FIGS. 8K-8N  illustrate an example of adjusting the appearance of current selection indicator  1514  in response to determining that a respective contact (e.g.,  1515 - 1  or  1515 - 2 ) has exceeded the respective intensity threshold.  FIG. 8K  illustrates an initial state of current selection indicator  1514  at initial position  1514 - a  indicating that masked image  1502  will be adjusted. In  FIG. 8L , in accordance with a determination that a respective contact (e.g.,  1515 - 1  or  1515 - 2 ) has a maximum intensity that is above a respective intensity threshold (e.g., “IT D ”), original image  1516  is revealed and continuous animation of current selection indicator  1514  occurs. In this instance, continuous animation of current selection indicator  1514  includes the handles moving from an initial position (e.g., position  1514 - a  in  FIG. 8L ) indicating that masked image  1502  will be adjusted through one or more intermediate positions (e.g., position  1514 - b  in  FIG. 8M ) to an end position (e.g., position  1514 - c  in  FIG. 8N ) indicating that original image  1516  will be adjusted. 
     It should be understood that the particular order in which the operations in  FIGS. 9A-9C  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method  1600  described above with respect to  FIGS. 9A-9C . For example, the gestures, contacts, intensity thresholds, images, image masks, and focus selectors described above with reference to method  1600  optionally have one or more of the characteristics of the gestures, contacts, intensity thresholds, images, image masks, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here. 
     In accordance with some embodiments,  FIG. 10  shows a functional block diagram of an electronic device  1700  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 10  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. As shown in  FIG. 10 , an electronic device  1700  includes a display unit  1702  configured to a masked image, wherein the masked image corresponds to an original image that is at least partially hidden in accordance with a corresponding image mask; a touch-sensitive surface unit  1704  configured to receive user gestures; one or more sensor units  1705  configured to detect intensity of contacts with the touch-sensitive surface unit; and a processing unit  1706  coupled to the display unit  1702 , the touch-sensitive surface unit  1704 , and the sensor units  1705 . In some embodiments, the processing unit includes a detecting unit  1708 , a display enabling unit  1710 , a modifying unit  1712 , and an adjusting unit  1714 . 
     The processing unit  1706  is configured to detect a gesture (e.g., with the detecting unit  1708 ) that includes a contact on the touch-sensitive surface unit while a focus selector is over the masked image, and movement of the contact across the touch-sensitive surface unit. The processing unit  1706  is further configured to respond to detecting the gesture, in accordance with a determination that the contact has a maximum intensity that is below a respective intensity threshold during the gesture, by modifying the masked image in accordance with the gesture (e.g., with the modifying unit  1712 ), wherein modifying the masked image includes concurrently modifying the image mask and the original image; and in accordance with a determination that the contact reaches an intensity during the gesture that is above the respective intensity threshold, by adjusting the original image relative to the image mask in accordance with the gesture (e.g., with the adjusting unit  1714 ). 
     In some embodiments, adjusting the original image relative to the image mask in accordance with the gesture includes adjusting the original image without modifying the image mask (e.g., with the adjusting unit  1714 ). 
     In some embodiments, the masked image is displayed in an electronic document on the display unit  1702 , the gesture includes lateral movement of the contact across the touch-sensitive surface unit  1704 , modifying the masked image in accordance with the gesture (e.g., with the modifying unit  1712 ) includes repositioning the masked image within the electronic document in accordance with the lateral movement of the contact on the touch-sensitive surface unit, and adjusting the original image relative to the image mask in accordance with the gesture (e.g., with the adjusting unit  1714 ) includes repositioning the original image relative to the image mask in accordance with the lateral movement of the contact on the touch-sensitive surface unit, without moving the image mask within the electronic document. As a result of this repositioning, a different portion of the original image is shown inside the image mask. 
     In some embodiments, the masked image is displayed in an electronic document on the display unit  1702 , the gesture includes a plurality of contacts and movement of the plurality of contacts relative to each other on the touch-sensitive surface unit  1704 , modifying the masked image in accordance with the gesture (e.g., with the modifying unit  1712 ) includes resizing the masked image within the electronic document in accordance with the movement of the plurality of contacts relative to each other on the touch-sensitive surface unit, and adjusting the original image relative to the image mask in accordance with the gesture (e.g., with the adjusting unit  1714 ) includes resizing the original image relative to the image mask in accordance with the movement of the plurality of contacts relative to each other on the touch-sensitive surface unit  1704 , without resizing the image mask within the electronic document. 
     In some embodiments, the processing unit  1706  is further configured to enable display (e.g., with the display enabling unit  1710 ) of a current selection indicator that indicates a user interface object that will be adjusted in accordance with the gesture. 
     In some embodiments, while the contact has an intensity below the respective intensity threshold, the current selection indicator indicates that the masked image will be adjusted in accordance the gesture. Furthermore, the processing unit  1706  is configured detect (e.g., with the detecting unit  1708 ) an increase in intensity of the contact above the respective intensity threshold and to respond to detecting the increase in intensity of the contact above the respective intensity threshold, by adjusting (e.g., with the adjusting unit  1714 ) the appearance of the current selection indicator to indicate that the original image will be adjusted in accordance with the gesture. 
     In some embodiments, adjusting the appearance of the current selection indicator (e.g., with the adjusting unit  1714 ) includes displaying a continuous animation of a set of resizing handles moving from an a first boundary indicating an extent of the masked image on the display unit to a second boundary indicating an extent of the original image on the display unit  1702 . 
     In some embodiments, the processing unit  1706  is further configured, prior to detecting the gesture, to operate in a masked-image-manipulation mode in which the mask and the original image are modified together; and in response to detecting that the contact has an intensity over the respective intensity threshold (e.g., with the detecting unit  1708 ), to operate in a mask-edit mode where the mask and the original image can be modified independently of each other. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 9A-9C  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 10 . For example, detection operation  1604 , modifying operation  1612 , and adjusting operation  1614  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally utilizes or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
     Word Spelling Correction 
     When a user is editing text in an electronic document, the user may wish to correct spelling of a misspelled word in the text, some applications have separate spelling correction interfaces that are accessed through a complex sequence of gestures or other inputs however these interfaces are cumbersome and inefficient for correcting spelling errors. In some methods, the user would edit the misspelled word manually or move a focus selector over the word and activate a spelling correction that provides candidate words for correcting the spelling. This process involves multiple steps on the part of the user, and thus can be tedious and time-consuming. The embodiments below improve on these methods by allowing the user to activate correction of a misspelled word by, while a focus selector is located over the misspelled word, performing a gesture with contact that meets predefined intensity criteria. If the contact meets the predefined intensity criteria, the misspelled word is automatically corrected. This makes text editing more efficient by allowing the user to correct misspelled words more quickly. 
       FIGS. 11A-11DD  illustrate exemplary user interfaces for word spelling correction in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 12A-12D .  FIGS. 11A-11DD  include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including one or more of a word replacement intensity threshold (e.g., “IT D ”), a first word preview intensity threshold (e.g., “IT 1 ”), a second word preview intensity threshold (e.g., “IT 2 ”), a correction-cancellation intensity threshold (e.g., “IT C ”) and a light press intensity threshold (e.g., “IT L ”). 
       FIG. 11A  illustrates user interface  3000  displayed on display  450  (e.g., display  340 ) of a device (e.g., device  300 ). User interface  3000  is an interface corresponding to an application. For example, user interface  3000  is, optionally, an interface corresponding to a web browser application, text editor application, word processor application, note application, messaging (e.g., email, chat) application, e-book application, or document reader application. User interface  3000  as shown in  FIG. 11A  is an email composition user interface for an email application. 
     User interface  3000  includes text display area  3001 , in which textual content, such as words  3002 , is, optionally, displayed. In some embodiments, words  3002  are part of electronic document  3003  (for example, text document, word processor document, email message, web page, electronic book). Words  3002  include word “revidions”  3002 - 1 , which is misspelled, as determined by the device. A word displayed in text display area  3001  (e.g., word  3002 ) is, optionally, determined to be misspelled in accordance with a spell check function on the device, which compares words  3002  to word entries in a dictionary (e.g., a dictionary stored in the memory  370  of the device. 
     In some embodiments, words  3002  that are determined to be misspelled are, optionally, displayed with visual indication of their status as misspelled words. For example, a word  3002  determined to be misspelled is, optionally, displayed with underlining, different font size, different font color, bold font, italics, highlighting, and so on. For example, word  3002 - 1  is misspelled and is thus underlined in  FIG. 11A . The style of the underlining is, optionally, single underline, double underline, dotted underline, wavy underline, etc. 
     Cursor  3004  (for example, a mouse pointer) is also displayed in user interface  3000 . Cursor  3004  is an example of a focus selector. A user optionally uses an input device (e.g., mouse  350 , touchpad  355  or other touch-sensitive surface) to move cursor  3004  to different locations in user interface  3000 . For example,  FIG. 11A  shows cursor  3004  displayed over text display area  3001 , and the device detects a gesture including movement of contact  3006  across touch-sensitive surface  451  (e.g., touchpad  355 ) of the device (e.g., while an intensity of contact  3006  is between a contact-detection intensity threshold IT 0  and a light press intensity threshold IT L ), as shown in  FIGS. 11A-11B .  FIG. 11B  shows cursor  3004  located over word  3002 - 1  with contact  3006  still detected on touch-sensitive surface  451 . While cursor  3004  is located over word  3002 - 1 , the gesture is, optionally, ended by lifting contact  3006  off touch-sensitive surface  451 . 
     In some embodiments, when cursor  3004  is moved over word  3002 - 1 , a haptic indication is, optionally, provided. The haptic indication indicates to the user that performing a gesture that satisfies predefined intensity criteria (described below) on misspelled word  3002 - 1  will cause correction of the misspelled word. For example, in  FIG. 11B , in response to detecting movement of the focus selector (e.g., cursor  3006 ) over word  3002 - 1 , the device generates tactile output  3005  (e.g., a vibration or other movement of the touch-sensitive surface  451 ) to provide an indication that word  3002 - 1  is responsive to a gesture including a contact with an intensity above the respective threshold (e.g., “IT D ”). 
     While cursor  3004  is positioned over word  3002 - 1 , the device monitors an intensity of contact  3006  to determine whether or not contact  3006  meets one or more predefined intensity criteria. In some embodiments, the predefined intensity criteria are met when a contact has an intensity above a word replacement intensity threshold at a predefined time relative to liftoff of the contact. For example, the intensity of contact  3006  at a predefined time prior to liftoff (e.g., 10 ms) is determined to evaluate whether the predefined intensity criteria are met. In some embodiments, the predefined intensity criteria are met when the contact has an intensity above the word replacement intensity threshold (e.g., “IT D ”) at any time during the gesture (while cursor  3004  is located over word  3002 - 1 ) prior to detecting liftoff of the contact. For example, the intensity of contact  3006  just prior to liftoff is determined to evaluate whether the predefined intensity criteria are met. As another example, the maximum intensity of contact  3006  prior to liftoff is determined to evaluate whether the predefined intensity criteria are met. 
     In  FIG. 11B , contact  3006  is a contact that does not meet the predefined intensity criteria (e.g., contact  3006  has a maximum intensity below IT D ). In  FIGS. 11C-11D , the device detects a press input including an increase in intensity of contact  3006  from an intensity below a light press intensity threshold (e.g., “IT L ”) to an intensity above the light press intensity threshold (e.g., “IT L ”) as shown in  FIG. 11C  and a decrease in intensity of contact  3006  below the light press intensity threshold (e.g., “IT L ”) as shown in  FIG. 11D . In response to detecting the gesture performed with contact  3006 , when an end of the gesture (e.g., liftoff of contact  3006  or a reduction in intensity of the contact below IT L ) is detected, a user interface for interacting with word  3002 - 1  within text display area  3001  is displayed. 
     In some embodiments, the use interface for interacting with word  3002 - 1  includes a text cursor, insertion point, or the like. For example, text cursor  3008  is, optionally, displayed near word  3002 - 1  (for example, at the beginning or end of word  3002 - 1 , within word  3002 - 1 ) in response to detection of the increase in intensity of contact  3006  from an intensity below a light press intensity threshold (e.g., “IT L ”) to an intensity above the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11C . Text cursor  3008  indicates a current location in words  3002  at which the user optionally enters additional characters or delete characters. 
     In some embodiments, the use interface for interacting with word  3002 - 1  includes an affordance for a replacement word that, when activated, replaces word  3002 - 1  with the replacement word. For example, replacement word affordance  3010  is, optionally, displayed near word  3002 - 1  in response to detection of the decrease in intensity of contact  3006  from an intensity above the light press intensity threshold (e.g., “IT L ”) to an intensity below the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11D . Replacement word affordance  3010  includes a suggested replacement word (“revisions”) for word  3002 - 1 . The replacement word is, optionally, a word that corrects the spelling of word  3002 - 1  or auto-completes word  3002 - 1 . The user optionally activates replacement word affordance  3010  by positioning cursor  3004  over replacement word affordance  3010  and performing a gesture (e.g., a tap gesture or a press input) on touch-sensitive surface  451  while cursor  3004  is located over replacement word affordance  3010 . In response to the activation of replacement word affordance  3010 , word “revisions”  3002 - 1  would be replaced with word “revisions.” 
     In some embodiments, the user interface for interacting with word  3002 - 1  includes one or more affordances  3012  for interacting with word  3002 - 1 . For example, “Cut” affordance  3012 - 1 , “Copy” affordance  3012 - 2 , and “Paste” affordance  3012 - 3  is, optionally, displayed, as shown in  FIG. 11E . A user optionally activates “Cut” affordance  3012 - 1  to copy word  3002 - 1  (e.g., to a virtual clipboard for pasting elsewhere) and to delete word  502 - 1  from words  3002 . A user optionally activates “Copy” affordance  3012 - 2  to copy word  3002 - 1  (e.g., to a virtual clipboard for pasting elsewhere). A user optionally activates “Paste” affordance  3012 - 3  to insert previously copied text (e.g., text copied into a virtual clipboard) to replace word  3002 - 1 . 
     Other examples of affordances for interacting with word  3002 - 1  include, for example, “Highlight” affordance  3012 - 4 , “Add Note” affordance  3012 - 5 , “Search Document” affordance  3012 - 6 , and “Search” affordance  3012 - 7 , as shown in  FIG. 11F . A user optionally activates “Highlight” affordance  3012 - 4  to highlight (e.g., with yellow or green color) word  3002 - 1 . A user optionally activates “Add Note” affordance  3012 - 5  to create a note to be associated with word  3002 - 1 . A user optionally activates “Search Document” affordance  3012 - 6  to search electronic document  3003  or words  3002  using word  3002 - 1  as a search term. A user optionally activates “Search” affordance  3012 - 7  to search an information repository (e.g., a search engine, an online encyclopedia) using word  3002 - 1  as a search term. 
     In some embodiments, the use interface for interacting with word  3002 - 1  includes an affordance for launching a spelling correction interface. For example, spelling correction affordance  3014  is, optionally, displayed near word  3002 - 1  in response to detection of the gesture, as shown in  FIG. 11G . When spelling correction affordance  3014  is activated, a spelling correction interface is launched, as shown in  FIG. 5H . The spelling correction interface optionally includes one or more options  3016  (e.g., one or more candidate replacement words) for correcting the spelling of word  3002 - 1 . The user optionally activates one of the options  3016  to replace word  3002  with a replacement word corresponding to the activated option  3016 . In some embodiments, the spelling correction affordance includes the one or more options  3016  (e.g., one or more candidate replacement words) for correcting the spelling of word  3002 - 1 , as shown in  FIG. 11H . 
       FIG. 11I  shows, instead of the gesture performed with contact  3006 , a gesture performed with contact  3018  detected on touch-sensitive surface  451 . As with  FIG. 11A , if cursor  3004  is not already located over word  3002 - 1 , the gesture optionally includes movement of contact  3018  to move cursor  3004  to a location over word  3002 - 1  (e.g., while an intensity of contact  3018  is between a contact-detection intensity threshold IT 0  and a light press intensity threshold IT L ).  FIG. 11J  shows cursor  3004  located over word  3002 - 1  with contact  3018  (and the corresponding gesture) still detected on touch-sensitive surface  451 . While cursor  3004  is located over word  3002 - 1 , the gesture is, optionally, ended by lifting contact  3018  off touch-sensitive surface  451 . 
     In some embodiments, when cursor  3018  is moved over word  3002 - 1 , a haptic indication is, optionally, provided. The haptic indication indicates to the user that performing a gesture that satisfies the predefined intensity criteria on misspelled word  3002 - 1  will cause correction of the misspelled word. For example, in  FIG. 11J , in response to detecting movement of the focus selector (e.g., cursor  3006 ) over word  3002 - 1 , the device generates tactile output  3005  (e.g., a vibration or other movement of the touch-sensitive surface  451 ) to provide an indication that word  3002 - 1  is responsive to a gesture including a contact with an intensity above the respective threshold (e.g., “IT D ”). 
     While cursor  3004  is positioned over word  3002 - 1 , the device monitors an intensity of contact  3018  to determine whether or not contact  3018  meets one or more predefined intensity criteria. In  FIG. 11J , contact  3018  meets the predefined intensity criteria (e.g., contact  3006  has an intensity above IT D ). For example, as shown in  FIG. 11I  the intensity of contact  3018  is below the word replacement intensity threshold (e.g., “IT D ”) prior to cursor  3004  being located over word  3002 - 1 , and the intensity of contact  3018  is increased from an intensity below the word replacement intensity threshold (e.g., “IT D ”), as shown in  FIG. 11J , to an intensity above the word replacement intensity threshold (e.g., by the user pressing harder on touch-sensitive surface  451  with contact  3018  to increase the intensity of contact  3018  over IT, as shown in  FIG. 11K ) while cursor  3004  is located over word  3002 - 1 . While cursor  3004  is located over word  3002 - 1 , the gesture is, optionally, ended by lifting contact  3018  off touch-sensitive surface  451 . 
     In response to detecting the gesture performed with contact  3018 , when a increase in intensity of contact  3018  from an intensity below the word replacement intensity threshold (e.g., “IT D ”) to an intensity above the word replacement intensity threshold (e.g., “IT D ”) is detected, the spelling of word  3002 - 1  is corrected, as shown in  FIG. 11K . In some embodiments, the spelling of word  3002 - 1  is corrected in response to detecting an end of the gesture (e.g., detecting liftoff of contact  3018  or detecting a decrease in intensity of contact  3018  from an intensity above IT D  to an intensity below IT L ). For example, the originally misspelled word  3002 - 1  “revidions” is replaced with correctly-spelled “revisions,” as shown in  FIG. 11K . After the correction, visual indication of misspelling (e.g., dotted underline) for word  3002 - 1  ceases to be displayed. 
     In some embodiments, the replacement word (e.g., “revisions”) that replaces the originally misspelled word  3002 - 1  (“revidions”) is a highest ranked candidate replacement word amongst multiple candidate replacement words. The highest ranked candidate replacement word is, optionally, determined by the device. For example, the device determines multiple candidate replacement words for the misspelled word (e.g., identifying words in a dictionary that are within an edit distance threshold from the misspelled word), ranks the multiple candidate replacement words (e.g., based on usage frequency and/or edit distance from the misspelled word), and selects the highest ranked candidate replacement word from the multiple candidate replacement words. 
     In some embodiments, a plurality of previews of the replacement words for misspelled word  3002 - 1  are, optionally, displayed prior to the actual replacement of misspelled word  3002 - 1  with a replacement.  FIG. 11L  shows contact  3018 , continuing the gesture shown in  FIG. 11I . In  FIG. 11J , the intensity of contact  3018  is determined to be below a first word preview intensity threshold (e.g., “IT 1 ”). In  FIG. 11L , the intensity of contact  3018  is determined to exceed the first word preview intensity threshold (e.g., “IT 1 ”). In response to the determination that the intensity of contact  3018  exceeds the first word preview intensity threshold (e.g., “IT 1 ”), word preview  3020 - 1  (“revisions”) is displayed in place of misspelled word  3002 - 1 . Word preview  3020 - 1  shows a preview of a first candidate replacement word that corrects misspelled word  3002 - 1 . Word preview  3020 - 1  is, optionally, displayed with different visual styling (e.g., bold font, different font size, different font color, etc.) than other words adjacent to the word preview in the block of text to emphasize that it is a preview of the replacement word and that the replacement of word  3002 - 1  has not occurred yet. In some embodiments, the first word preview intensity threshold is also the word replacement intensity threshold (e.g., the first word preview intensity threshold is IT D ) for the first candidate replacement word shown in word preview  3020 - 1 ; if the gesture with contact  3018  ends (e.g., by detecting liftoff of contact  3018  or a reduction in intensity of contact  3018  below IT L ), word  3002 - 1  is replaced with the word in word preview  3020 - 1  (e.g., “revisions). 
     The intensity of contact  3018  is, optionally, increased further to exceed a second word preview intensity threshold (e.g., “IT L ”) that is higher than the first word preview intensity threshold (e.g., “IT 1 ”), as shown in  FIG. 11M . In response to the determination that the intensity of contact  3018  exceeds the second word preview intensity threshold (e.g., “IT 2 ”), word preview  3020 - 2  (e.g., “revision”) is displayed in place of word preview  3020 - 1 , as shown in  FIG. 11M . Word preview  3020 - 2  previews shows a preview of a second candidate replacement word that corrects misspelled word  3002 - 1 . As with word preview  3020 - 1 , word preview  3020 - 2  is, optionally, displayed with different visual styling (e.g., bold font, different font size, different font color, etc.) than other words adjacent to the word preview in the block of text to emphasize that the replacement of word  3002 - 1  has not occurred yet. In some embodiments, the second word preview intensity threshold (e.g., “IT 2 ”) is also a word replacement intensity threshold for the second candidate replacement word shown in word preview  3020 - 2 ; if the gesture with contact  3018  ends (e.g., by detecting liftoff of contact  3018  or a reduction in intensity of contact  3018  below IT L ), word  3002 - 1  is replaced with the word in word preview  3020 - 2 . 
     In some circumstances, the device detects a decrease in the intensity of contact  3018  from an intensity above the first word preview intensity threshold (e.g., “IT 1 ”) or the second word preview intensity threshold (e.g., “IT 2 ”) to a lower intensity below the first word preview intensity threshold (e.g., “IT 1 ”) or the second word preview intensity threshold (e.g., “IT 2 ”) prior to liftoff of contact  3018  (or prior to reduction of intensity of contact  3018  to an intensity below IT L ).  FIGS. 11L and 11N  show contact  3018  with an intensity that is decreased from above the first word preview intensity threshold (e.g., “IT 1 ”) to an intensity that is below a correction-cancellation intensity threshold (e.g., “IT C ”). The intensity that is below the correction-cancellation intensity threshold (e.g., “IT C ”) is maintained for at least a predefined amount of time (e.g., 1-2 seconds) before detecting an end of the gesture (e.g., liftoff of contact  3018  or a decrease in intensity of contact  3018  below IT L ). In some embodiments, the correction-cancellation intensity threshold and the first word preview intensity threshold are the same (e.g., the correction-cancellation intensity threshold and the first word preview intensity threshold are both IT D  or are both IT 1  for the first replacement word). In some other embodiments, the correction-cancellation intensity threshold (e.g., “IT C ”) and the first word preview intensity threshold (e.g., “IT 1 ”) are different. In response to detection of the decrease in intensity of contact  3018  below the correction-cancellation intensity threshold (e.g., “IT C ”) and maintenance of the intensity of contact  3018  below the correction-cancellation intensity threshold (e.g., “IT C ”) for at least a predefined time before detecting an end of the gesture (e.g., liftoff of contact  3018  or a decrease in intensity of contact  3018  below IT L ), word preview  3020 - 1  ceases to be displayed and word  3002 - 1  is displayed again, as shown in  FIG. 11N . 
     After word preview  3020 - 1  ceases to be displayed, intensity of contact  3018  is, optionally reduced to an intensity below IT L  (or contact  3018  is lifted off touch-sensitive surface  451 ), ending the gesture. In response to detection of the end of the gesture, a user interface (e.g., affordances  3012 ) for interacting with word  3002 - 1  is, optionally, displayed, as shown in  FIG. 11O . 
       FIG. 11P  shows electronic document  3003  with words  3002  displayed in text display area  3001 . Cursor  3004  is displayed on display  450  as well. Words  3002  includes misspelled words  3002 - 1  “revidions” and  3002 - 2  “suggestions.” A gesture with contact  3024  is detected on touch-sensitive surface  451 . The gesture includes movement of contact  3024  (e.g., while contact has an intensity between IT L  and IT D ) that selects selection  3026  ( FIG. 11Q ) of a set of one or more words in words  3002  and moves cursor  3004  to a position over word  3002 - 1 , as shown in  FIG. 11Q . 
       FIG. 11Q  shows selection  3026  of a set of one or more words  3002 . Included in the word selection  3026  are words  3002 - 1  and  3002 - 2 . In some circumstances, the user changes the intensity of contact  3024  so that contact  3024  meets the predefined intensity criteria, as shown in  FIG. 11R , where contact  3024  has an intensity above a word replacement intensity threshold (e.g., “IT D ”). In response to detecting the gesture, in accordance with a determination that contact  3024  meets the predefined intensity criteria, words  3002 - 1  and  3002 - 2  within selection  3026  are both replaced with replacement words that correct their respective spelling, as shown in  FIG. 11R . 
       FIG. 11S  shows words  3002  with misspelled words  3002 - 1  and  3002 - 2 , as in  FIG. 11P . A gesture with contact  3028  is detected on touch-sensitive surface  451 . The gesture includes movement of contact  3028  (e.g., while contact has an intensity between IT L  and IT D ) that selects a selection  3026  ( FIG. 11T ) of a set of one or more words in words  3002  and moves cursor  3004  to a position over word  3002 - 1 , as shown in  FIG. 11T . 
       FIG. 11T  shows selection  3026  of a set of one or more words  3002 . Included in the word selection  3026  are words  3002 - 1  and  3002 - 2 . Contact  3028  does not meet the predefined intensity criteria, as shown in  FIG. 11T . In response to detecting the gesture, in accordance with a determination that contact  3028  does not meet the predefined intensity criteria, as shown in  FIGS. 11S-11U  where contact  3024  has a maximum intensity below the word replacement intensity threshold (e.g., “IT D ”), a user interface for interacting with selection  3026  is, optionally, displayed, as shown in  FIG. 11U  after detecting an end of the gesture (e.g., liftoff of contact  3028  or a reduction in intensity of contact  3028  to an intensity below IT L ). For example,  FIG. 11U  shows affordances  3012 - 1  thru  3012 - 3  that act on selection  3026  (or the text in selection  3026 ), not just word  3002 - 1 . 
     Returning to and continuing from  FIG. 11K ,  FIGS. 11V-11W  show, after word  3002 - 1  has been corrected with a replacement word, a new gesture with contact  3030  detected on touch-sensitive surface  451  while cursor  3004  is positioned over word  3002 - 1 . In  FIG. 11V  contact  3030  has an intensity below the word replacement intensity threshold (e.g., “IT D ”) and in  FIG. 11W , the intensity of contact  3030  is increased to an intensity over the word replacement intensity threshold (e.g., “IT D ”) and thus the gesture including contact  3030  meets the predefined intensity criteria. 
     In response to detecting the gesture performed with contact  3030 , corrected word  3002 - 1  is replaced with another replacement word. For example, the corrected word  3002 - 1  “revisions” is replaced with “revision,” which is also correctly spelled, as shown in  FIG. 11V . In some embodiments, the corrected word is replaced with another replacement word during the gesture (e.g., in response to detecting the increase in intensity of contact  3030  above the word replacement intensity threshold). In some embodiments, the corrected word is replaced with another replacement word in response to detecting a end of the gesture (e.g., in response to detecting liftoff of contact  3030  or in response to detecting a decrease in intensity of contact  3030  from an intensity above the word replacement intensity threshold to an intensity below the word replacement intensity threshold. 
       FIGS. 11X-11Y  show, as in  FIG. 11V , after word  3002 - 1  has been corrected with a replacement word, a gesture with contact  3032  (instead of contact  3030 ) detected on touch-sensitive surface  451  while cursor  3004  is positioned over word  3002 - 1 . The gesture performed with contact  3032  includes detecting an increase in intensity of contact  3032  from an intensity below a light press intensity threshold (e.g., “IT L ”) to an intensity above the light press intensity threshold (e.g., “IT L ”). Contact  3032  does not meet the predefined intensity criteria (e.g., because a maximum intensity of contact  3032  in  FIGS. 11X-11Y  is below the word replacement intensity threshold). In response to detecting the gesture performed with contact  3032 , cursor  3008  is placed within the corrected word  3002 - 1  and displayed, as shown in  FIG. 11Y . In some embodiments, the cursor is placed within the corrected word during the gesture (e.g., in response to detecting the increase in intensity of contact  3032  above the light press intensity threshold). In some embodiments, the cursor is placed within the corrected word in response to detecting a end of the gesture (e.g., in response to detecting liftoff of contact  3032  or in response to detecting a decrease in intensity of contact  3032  from an intensity above the light press intensity threshold to an intensity below the light press intensity threshold. 
       FIGS. 11Z-11DD  illustrate examples of the user interfaces described above, with reference to  FIGS. 11A-11Y , implemented on a device (e.g., device  100 ) with a touch-sensitive display  112 .  FIG. 11Z  illustrates user interface  3040  displayed on touch-sensitive display  112  (e.g., display  112 ) of a device (e.g., device  100 ). User interface  3040  includes text display area  3041 , in which textual content, such as words  3042 , is, optionally, displayed. In some embodiments, words  3042  are part of electronic document  3043  (for example, text document, word processor document, email message, web page, electronic book). Words  3042  include word “revidions”  3042 - 1 , which is misspelled as determined by the device. Word  3042 - 1  is displayed with underlining to indicate that it has been determined by the device to be a misspelling. 
     A gesture performed with contact  3046  is detected on touch-sensitive display  112  at a location over word  3042 - 1 . The gesture includes increase in intensity of contact  3046  from an intensity below a light press intensity threshold (e.g., “IT L ”) in  FIG. 11Z  to an intensity above the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11AA . In some embodiments, the device detects an end of the gesture performed with contact  3046  when the intensity of contact  3046  decreases below the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11B . In some embodiments, the device detects an end of the gesture performed with contact  3046  when the device detects liftoff of contact  3046  from touch-sensitive display  112 . 
     In some embodiments, when contact  3046  is detected over word  3042 - 1 , a haptic indication is, optionally, provided. The haptic indication indicates to the user that performing a gesture that satisfies predefined intensity criteria (described below) on misspelled word  3042 - 1  will cause correction of the misspelled word. For example, when contact  3046  is detected on touch-sensitive display  112  over word  3042 - 1 , a detent or slight vibration of touch-sensitive display  112  is, optionally, generated. 
     While contact  3046  is detected over word  3042 - 1  the device monitors an intensity of contact  3046  to determine whether or not contact  3046  meets one or more predefined intensity criteria. In some embodiments, the predefined intensity criteria are met when a contact has an intensity above a “word replacement intensity threshold” at a predefined time relative to liftoff of the contact. For example, the intensity of contact  3046  at a predefined time prior to liftoff (e.g., 10 ms) is determined to evaluate whether the predefined intensity criteria are met. In some embodiments, the predefined intensity criteria are met when the contact has an intensity above the word replacement intensity threshold (e.g., “IT D ”) at any time during the gesture (while contact  3046  is detected over word  3042 - 1 ) prior to detecting liftoff of the contact. For example, the intensity of contact  3046  just prior to liftoff is determined to evaluate whether the predefined intensity criteria are met. As another example, the maximum intensity of contact  3046  prior to liftoff is determined to evaluate whether the predefined intensity criteria are met. 
     In  FIG. 11Z , contact  3046  is a contact that does not meet the predefined intensity criteria (e.g., contact  3046  has a maximum intensity below IT D ). In  FIGS. 11Z-11BB , the device detects a press input including an increase in intensity of contact  3006  from an intensity below a light press intensity threshold (e.g., “IT L ”) to an intensity above the light press intensity threshold (e.g., “IT L ”) as shown in  FIG. 11AA  and a decrease in intensity of contact  3006  below the light press intensity threshold (e.g., “IT L ”) as shown in  FIG. 11BB . In response to detecting the gesture performed with contact  3046 , when liftoff of contact  3046  (ending the gesture) is detected, a user interface for interacting with word  3042 - 1  within text display area  3041  is displayed. 
     In some embodiments, the use interface for interacting with word  3042 - 1  includes a text cursor, insertion point, or the like. For example, text cursor  3048  is, optionally, displayed near word  3042 - 1  (for example, at the beginning or end of word  3042 - 1 , within word  3042 - 1 ) in response to detection of the increase in intensity of contact  3006  from an intensity below a light press intensity threshold (e.g., “IT L ”) to an intensity above the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11AA . Text cursor  3048  indicates a current location in words  3042  at which the user optionally enters additional characters or delete characters. 
     In some embodiments, the use interface for interacting with word  3042 - 1  includes one or more affordances  3052  for interacting with word  3042 - 1 . For example, “Cut” affordance  3052 - 1 , “Copy” affordance  3052 - 2 , and “Paste” affordance  3052 - 3  is, optionally, displayed near word  3042 - 1  in response to detection of the decrease in intensity of contact  3046  from an intensity above the light press intensity threshold (e.g., “IT L ”) to an intensity below the light press intensity threshold (e.g., “IT L ”), as shown in  FIG. 11BB . A user optionally activates “Cut” affordance  3052 - 1  to copy word  3042 - 1  (e.g., to a virtual clipboard for pasting elsewhere) and to delete word  542 - 1  from words  3042 . A user optionally activates “Copy” affordance  3052 - 2  to copy word  3042 - 1  (e.g., to a virtual clipboard for pasting elsewhere). A user optionally activates “Paste” affordance  3052 - 3  to insert previously copied text (e.g., text copied into a virtual clipboard) to replace word  3042 - 1 . 
     The user interfaces for interacting with word  3042 - 1  within text display area  3041 , described above with reference to  FIGS. 11AA-11BB , are but a few examples. Other user interfaces for interacting with word  3042 - 1 , such as the analogues to the user interfaces for interacting with word  3042 - 1  described above with reference to  FIGS. 11C-11H , are, optionally, displayed. 
       FIG. 11CC  shows, instead of the gesture performed with contact  3046 , a gesture performed with contact  3058  detected on touch-sensitive display  112 . Contact  3058  is detected over word  3042 - 1 . In some embodiments, when cursor  3058  is moved over word  3042 - 1 , a haptic indication is, optionally, provided. The haptic indication indicates to the user that performing a gesture that satisfies the predefined intensity criteria on misspelled word  3042 - 1  will cause correction of the misspelled word. For example, when contact  3058  is detected on touch-sensitive display  112  over word  3042 - 1 , a detent or slight vibration of touch-sensitive display  112  is, optionally, generated. 
     In  FIG. 11CC , contact  3058  meets the predefined intensity criteria. For example, in some circumstances, the intensity of contact  3058  is below the word replacement intensity threshold while contact  3058  is over word  3042 - 1  and the device detects an increase in intensity of contact  3058  from an intensity below a word replacement intensity threshold (e.g., “IT D ”) to an intensity above the word replacement intensity threshold (e.g., “IT D ”). While contact  3058  remains located over word  3042 - 1 , gesture is, optionally, ended by lifting contact  3058  off touch-sensitive display  3058  or be reducing the intensity of contact  3058  below a light press intensity threshold (e.g., “IT L ”). 
     In response to detecting the gesture with contact  3058  (e.g., in response to detecting the increase in intensity of contact  3058  above IT D , or in response to detecting an end of the gesture including liftoff of contact  3058  or a decrease in intensity of the contact below IT L ), the device corrects the spelling of word  3042 - 1 . For example, the originally misspelled word  3042 - 1  “revidions” is replaced with correctly-spelled “revisions,” as shown in  FIG. 11DD . After the correction, visual indication of misspelling (e.g., dotted underline) for word  3042 - 1  ceases to be displayed. 
       FIGS. 12A-12D  are flow diagrams illustrating a method  3100  of word spelling correction in accordance with some embodiments. The method  3100  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  3100  is, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  3100  provides an intuitive way to correct word spelling. The method reduces the cognitive burden on a user when correcting word spelling, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to correct word spelling faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 3102 ) a plurality of words on the display, where the plurality of words include a misspelled word. For example,  FIG. 11A  shows words  3002  displayed on display  450 . Words  3002  includes misspelled word  3002 - 1 .  FIG. 11Z  shows words  3042 , which includes misspelled word  3042 - 1 , displayed on touch-sensitive display  112 . 
     In some embodiments, prior to detecting the gesture, the device displays ( 3104 ) a visual indication that performing the gesture on the misspelled word will cause the misspelled word to be corrected (e.g., display a visual indication that the word is misspelled). For example, in  FIGS. 11A, 11I and 11Z  misspelled word  3002 - 1  is shown with underlining, to indicate that the word is misspelled. The underlining is, optionally, displayed before the gesture is detected. 
     In some embodiments, the device provides ( 3106 ) a haptic indication that performing the gesture on the misspelled word will cause the misspelled word to be corrected (e.g., by generating a detent or slight vibration of the touch-sensitive surface when the user moves the contact so that the focus selector moves over the misspelled word, indicating that applying pressure to the contact will cause the device to correct the misspelled word). For example, when cursor  3004  is moved over misspelled word  3002 - 1 , a tactile output, such as a detent or a slight vibration, is, optionally, generated on touch-sensitive surface  451 , as shown in  FIGS. 11B and 11J . 
     While a focus selector is at a location corresponding to the misspelled word, the device detects ( 3108 ) a gesture that includes a contact (e.g., a finger contact) on the touch-sensitive surface. For example,  FIGS. 11B-11D  show a gesture performed with contact  3006  while cursor  3004  is located over word  3002 - 1 , and  FIG. 11J  shows a gesture performed with contact  3018  while cursor  3004  is located over word  3002 - 1 . As another example,  FIG. 11Z  shows a gesture performed with contact  3046  while contact  3046  is over word  3042 - 1 . 
     In some embodiments, while detecting ( 3110 ) the gesture, the device determines ( 3112 ) that the contact has exceeded a first intensity threshold, and in response to determining that the contact has exceeded the first intensity threshold, displays ( 3114 ) a preview of a first correction for the misspelled word (e.g., a first replacement word).  FIG. 11L , for example, shows contact  3018  that exceeds a first word preview intensity threshold (e.g., “IT 1 ”). In response to a determination that contact  3018  exceeds the first word preview intensity threshold (e.g., “IT 1 ”), replacement word preview  3020 - 1  (e.g., “revisions”) is displayed in place of word  3002 - 1  (e.g., “revidions”). 
     In some embodiments, while detecting ( 3110 ) the gesture, the device determines ( 3116 ) that the contact has exceeded a second intensity threshold, where the second intensity threshold is higher than the first intensity threshold, and in response to determining that the contact has exceeded the second intensity threshold, displays ( 3118 ) a preview of a second correction (e.g., a second replacement word) for the misspelled word, wherein the second correction is different from the first correction.  FIG. 11M , for example, shows contact  3018  that exceeds a second word preview intensity threshold (e.g., “IT 2 ”) that is higher than the first word preview intensity threshold (e.g., “IT 2 ”). In response to a determination that contact  3018  exceeds the second word preview intensity threshold (e.g., “IT 2 ”), replacement word preview  3020 - 2  (e.g., “revision”), is displayed in place of word preview  3020 - 1  (e.g., “revisions”). 
     In some embodiments, after determining that the contact has exceeded ( 3120 ) the first intensity threshold and prior to detecting an end of the gesture, the device detects ( 3122 ) a decrease in intensity of the contact below a correction-cancellation intensity threshold and maintenance of the intensity of the contact below the correction-cancellation intensity threshold for at least a predefined time. In some embodiments, the correction-cancellation intensity threshold is the same as the first intensity threshold. In some embodiments, the correction-cancellation intensity threshold is different from the first intensity threshold (e.g., so as to provide some hysteresis for the correction selection and thereby reduce jitter when the contact intensity is close to the first intensity threshold). For example,  FIG. 11N  shows contact  3018  with an intensity that has decreased, from an intensity above a first word preview intensity threshold ( FIG. 11L ), below a correction-cancellation intensity threshold (e.g., “IT C ”). The intensity of contact  3018  is maintained below the correction-cancellation intensity threshold (e.g., “IT C ”) for at least a predefined time. 
     In response to detecting a decrease in intensity of the contact below the correction-cancellation intensity threshold and maintenance of the intensity of the contact below the correction-cancellation intensity threshold for at least the predefined time, the device ceases ( 3124 ) to display the preview of the first correction. In response to detection of the decrease in intensity of contact  3018  below the correction-cancellation intensity threshold and maintenance of the intensity below the correction-cancellation intensity threshold for at least the predefined time, word preview  3020 - 1  ceases to be displayed, as shown in  FIG. 11N . 
     After ceasing to display the preview of the first correction, the device detects ( 3126 ) an end of the gesture, and in response to detecting the end of the gesture, displays ( 3128 ) the user interface for interacting with the misspelled word within the plurality of words on the display (e.g., without correcting the misspelled word). Thus, in some embodiments, the user is able to preview the correction and slowly decrease intensity of the contact so as to “cancel” the correction. For example, after word preview  3020 - 1  ceases to be displayed, intensity of contact  3018  is decreased below a light press intensity threshold (e.g., “IT L ”) or, optionally contact  3018  is lifted off, ending the gesture. In response to detection of the end of the gesture, a user interface for interacting with word  3002 - 1  (for example, affordances  3012 - 1  thru  3012 - 3 ) is displayed, as shown in  FIG. 11O . 
     In response ( 3130 ) to detecting the gesture, in accordance with a determination that the contact met ( 3132 ) predefined intensity criteria, the device corrects the misspelled word. In some embodiments, the predefined intensity criteria are met ( 3134 ) when the contact had an intensity above a respective intensity threshold (e.g., the word replacement intensity threshold) at a predefined time relative to liftoff of the contact (e.g., the device evaluates the intensity of the contact 10 milliseconds prior to liftoff). Contact  3018 , for example, optionally meets the predefined intensity criteria by having an intensity above a word replacement intensity threshold (e.g., “IT D ”) at a predefined time prior to liftoff of contact  3018 . In some embodiments, the predefined intensity criteria are met ( 3136 ) when the contact had an intensity above a respective intensity threshold (e.g., the word replacement intensity threshold) at any time during the gesture prior to detecting liftoff of the contact (e.g., the device evaluates the maximum intensity of the contact prior to liftoff). Contact  3018 , for example, optionally meets the predefined intensity criteria by having a maximum intensity above the word replacement intensity threshold (e.g., “IT D ”) prior to liftoff of contact  3018 . 
     In some embodiments, correcting the misspelled word includes replacing ( 3138 ) the misspelled word with a highest ranked candidate replacement word, where the highest ranked candidate replacement word is determined by: determining a plurality of candidate replacement words for the misspelled word, ranking the plurality of candidate replacement words, and selecting the highest ranked candidate replacement word from the plurality of candidate replacement words. For example, the replacement word “revisions” that replaces the misspelled word  3002 - 1  “revidions” in  FIGS. 11J-11K  is, optionally, a highest ranked candidate replacement word amongst multiple candidate replacement words. The candidate replacement words are, optionally, determined from a dictionary on device  300  and ranked according to, for example, usage frequency and edit distance to the originally misspelled word. In some embodiments, the determining, ranking, and selecting steps typically occur prior to detecting the gesture, rather than in response to detecting the gesture. Thus, in some embodiments, for a given misspelled word, the device determines the highest ranked candidate replacement word prior to detecting the gesture that corrects the misspelling. 
     In contrast, in accordance with a determination that the contact did not meet the predefined intensity criteria, the device displays ( 3140 ) a user interface for interacting with the misspelled word within the plurality of words on the display. For example,  FIG. 11K  shows word  3002 - 1  corrected with the replacement word “revisions” in response to detection of the gesture with contact  3018 , which meets the predefined intensity criteria, while  FIGS. 11C-11H  show examples of user interfaces for interacting with word  3002 - 1  that are displayed in response to detection of the gesture with contact  3006 , which does not meet the predefined intensity criteria, as described in greater detail above. As another example,  FIG. 11DD  shows word  3042 - 1  corrected with the replacement word “revisions” in response to detection of the gesture with contact  3058 , which meets the predefined intensity criteria, while  FIGS. 11AA-11BB  show examples of user interfaces for interacting with word  3042 - 1  that are displayed in response to detection of the gesture with contact  3046 , which does not meet the predefined intensity criteria, as described in greater detail above. 
     In some embodiments, the user interface for interacting with the misspelled word within the plurality of words includes ( 3142 ) one or more of: an affordance for a replacement word that, when activated, replaces the misspelled word with the replacement word, a text cursor displayed proximate to the misspelled word, an affordance for copying and deleting the misspelled word (e.g., a “cut” button), an affordance for copying the misspelled word, an affordance for replacing the misspelled word with previously copied text (e.g., a paste button), an affordance for highlighting the misspelled word, an affordance for creating a note to be associated with the misspelled word, an affordance for searching the plurality of words using the misspelled word as a search term, an affordance for searching an information repository using the misspelled word as a search term (e.g., submitting the misspelled word to a search engine or Wikipedia), and an affordance for launching a spelling correction user interface for providing a plurality of options for correcting the misspelled word. The user interface for interacting with word  3002 - 1  is, optionally, text cursor  3008  ( FIG. 11C ), replacement word affordance  3010  ( FIG. 11D ), “Cut” affordance  3012 - 1  ( FIG. 11E ), “Copy” affordance  3012 - 2  ( FIG. 11E ), “Paste” affordance  3012 - 3  ( FIG. 11E ), “Highlight” affordance  3012 - 4  ( FIG. 11F ), “Add Note” affordance  3012 - 5  ( FIG. 11F ), “Search Document” affordance  3012 - 6  ( FIG. 11F ), “Search” affordance  3012 - 7  ( FIG. 11F ), and affordance  3014  ( FIG. 11G ) for launching spelling correction options  3016  ( FIG. 11H ). 
     In some embodiments, while the gesture is detected, a set of words including the misspelled word and one or more other misspelled words is selected ( 3146 ) (e.g., the user selects a paragraph or multiple paragraphs including multiple misspelled words and is able to correct all of the misspelled words in the selection at once by pressing on the selection). For example,  FIGS. 11P-11Q  shows selection  3026  of a plurality of words, including words  3002 - 1  and  3002 - 2 , while a gesture performed with contact  3024  is detected. Similarly,  FIGS. 11S-11T  shows selection  3026  a plurality of words, including words  3002 - 1  and  3002 - 2 , while a gesture performed with contact  3028  is detected. 
     In response to detecting the gesture, in accordance with a determination that the contact met predefined intensity criteria, the device corrects ( 3148 ) the misspelled word and the one or more other misspelled words, and in accordance with a determination that the contact did not meet the predefined intensity criteria, the device displays ( 3150 ) a user interface for interacting with the set of words within the plurality of words on the display. For example, in response to detecting the gesture performed with contact  3024  and in accordance with a determination that contact  3024  meets the predefined intensity criteria, words  3002 - 1  and  3002 - 2  are corrected with replacement words, as shown in  FIG. 11R . In response to detecting the gesture performed with contact  3028  and in accordance with a determination that contact  3028  does not meet the predefined intensity criteria, a user interface for interacting with selection  3026  (e.g., affordances  3012 ) is displayed, as shown in  FIG. 11U . 
     In some embodiments, correcting the misspelled word in response to the gesture includes displaying ( 3152 ) a first correction for the misspelled word (e.g., replacing the misspelled word with a first substitute word). After detecting the gesture, while a focus selector is at a location corresponding to the first correction for the misspelled word, the device detects ( 3154 ) a second gesture that includes a contact on the touch-sensitive surface. For example,  FIG. 11V  shows correction “revisions” displayed for word  3002 - 1  and, after the gesture with contact  3018  is detected, a second gesture with contact  3030  is detected on touch-sensitive surface  451  while cursor  3004  is over the corrected word  3002 - 1 .  FIG. 11X  shows the same thing, but the second gesture includes contact  3032  instead. Contact  3030  meets the predefined intensity criteria, and contact  3032  does not meet the predefined intensity criteria. 
     In response to detecting the second gesture ( 3156 ), in accordance with a determination that the contact in the second gesture met the predefined intensity criteria, the device displays ( 3158 ) a second correction for the misspelled word, where the second correction is different from the first correction (e.g., replacing the first correction for the misspelled word with a second substitute word different from the first correction for the misspelled word); and in accordance with a determination that the contact in the second gesture did not meet the predefined intensity criteria, the device places ( 3160 ) a text cursor within the first correction for the misspelled word. As shown in  FIG. 11W , for example, in response to detecting the gesture with contact  3030  and in accordance with the determination that contact  3030  meets the predefined intensity criteria, a different correction “revision” is displayed for word  3002 - 1  (e.g., replacing the previous correction “revisions”). In contrast, as shown in  FIG. 11Y , for example, in response to detecting the gesture with contact  3032  and in accordance with the determination that contact  3032  does not meet the predefined intensity criteria, cursor  3008  is placed and displayed within word  3002 - 1 . 
     In some embodiments, the methods described above with reference to a correction of a misspelled word are applied in an analogous manner to correcting a grammatical error in a sentence or correcting an improper word choice (e.g., replacing “their” with “there”). 
     It should be understood that the particular order in which the operations in  FIGS. 12A-12D  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method  3100  described above with respect to  FIGS. 12A-12D . For example, the contacts, gestures, intensity thresholds, focus selectors described above with reference to method  3100  optionally has one or more of the characteristics of the contacts, gestures, intensity thresholds, focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here. 
     In accordance with some embodiments,  FIG. 13  shows a functional block diagram of an electronic device  3200  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 13  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG. 13 , an electronic device  3200  includes a display unit  3202  configured to display a plurality of words, where the plurality of words include a misspelled word; a touch-sensitive surface unit  3204  configured to receive gestures, the gestures including contacts; one or more sensor units  3205  to detect intensity of contacts with the touch-sensitive surface unit  3204 ; and a processing unit  3206  coupled to the display unit  3202 , the touch-sensitive surface unit  3204  and the sensor units  3205 . In some embodiments, the processing unit  3206  includes a detecting unit  3208 , a correcting unit  3210 , a display enabling unit  3212 , a providing unit  3214 , a determining unit  3216 , a ceasing unit  3218 , and a placing unit  3220 . 
     The processing unit  3206  is configured to: while a focus selector is at a location corresponding to the misspelled word, detect a gesture that includes a contact on the touch-sensitive surface unit  3204  (e.g., with the detecting unit  3208 ). The processing unit  3206  is further configured to, in response to detecting the gesture: in accordance with a determination (e.g., with the determining unit  3216 ) that the contact met predefined intensity criteria, correct the misspelled word (e.g., with the correcting unit  3210 ); and in accordance with a determination (e.g., with the determining unit  3216 ) that the contact did not meet the predefined intensity criteria, enable display of a user interface for interacting with the misspelled word within the plurality of words on the display unit  3202  (e.g., with the display enabling unit  3212 ). 
     In some embodiments, the predefined intensity criteria are met when the contact had an intensity above a respective intensity threshold at a predefined time relative to liftoff of the contact. 
     In some embodiments, the predefined intensity criteria are met when the contact had an intensity above a respective intensity threshold at any time during the gesture prior to detecting liftoff of the contact. 
     In some embodiments, the user interface for interacting with the misspelled word within the plurality of words includes one or more of: an affordance for a replacement word that, when activated, replaces the misspelled word with the replacement word, a text cursor displayed proximate to the misspelled word, an affordance for copying and deleting the misspelled word, an affordance for copying the misspelled word, an affordance for replacing the misspelled word with previously copied text, an affordance for highlighting the misspelled word, an affordance for creating a note to be associated with the misspelled word, an affordance for searching the plurality of words using the misspelled word as a search term, an affordance for searching an information repository using the misspelled word as a search term, and an affordance for launching a spelling correction user interface for providing a plurality of options for correcting the misspelled word. 
     In some embodiments, correcting the misspelled word (e.g., with the correcting unit  3210 ) includes: replacing the misspelled word with a highest ranked candidate replacement word, where the highest ranked candidate replacement word is determined (e.g., with the determining unit  3216 ) by: determining a plurality of candidate replacement words for the misspelled word; ranking the plurality of candidate replacement words; and selecting the highest ranked candidate replacement word from the plurality of candidate replacement words. 
     In some embodiments, the processing unit  3206  is configured to: prior to detecting the gesture, enable display of a visual indication that performing the gesture on the misspelled word will cause the misspelled word to be corrected (e.g., with the display enabling unit  3212 ). 
     In some embodiments, the processing unit  3206  is configured to: provide a haptic indication that performing the gesture on the misspelled word will cause the misspelled word to be corrected (e.g., with the providing unit  3214 ). 
     In some embodiments, the processing unit  3206  is configured to: while detecting the gesture: determine that the contact has exceeded a first intensity threshold (e.g., with the determining unit  3216 ); and in response to determining that the contact has exceeded the first intensity threshold, enable display of a preview of a first correction for the misspelled word (e.g., with the display enabling unit  3212 ). 
     In some embodiments, the processing unit  3206  is configured to: while detecting the gesture: determine that the contact has exceeded a second intensity threshold, wherein the second intensity threshold is higher than the first intensity threshold (e.g., with the determining unit  3216 ); and in response to determining that the contact has exceeded the second intensity threshold, enable display of a preview of a second correction for the misspelled word (e.g., with the display enabling unit  3212 ), where the second correction is different from the first correction. 
     In some embodiments, the processing unit  3206  is configured to: after determining that the contact has exceeded the first intensity threshold and prior to detecting an end of the gesture: detect a decrease in intensity of the contact below a correction-cancellation intensity threshold and maintenance of the intensity of the contact below the correction-cancellation intensity threshold for at least a predefined time (e.g., with the detecting unit  3208 ); and in response to detecting a decrease in intensity of the contact below the correction-cancellation intensity threshold and maintenance of the intensity of the contact below the correction-cancellation intensity threshold for at least the predefined time, cease to display the preview of the first correction (e.g., with the ceasing unit  3218 ); and after ceasing to display the preview of the first correction, detect an end of the gesture (e.g., with the detecting unit  3208 ); and in response to detecting the end of the gesture, enable display of the user interface for interacting with the misspelled word within the plurality of words on the display unit  3202  (e.g., with the display enabling unit  3212 ). 
     In some embodiments, while the gesture is detected, a set of words including the misspelled word and one or more other misspelled words is selected; and the processing unit  3206  is configured to: in response to detecting the gesture: in accordance with a determination (e.g., with the determining unit  3216 ) that the contact met predefined intensity criteria, correct the misspelled word and the one or more misspelled words (e.g., with the correcting unit  3210 ); and in accordance with a determination (e.g., with the determining unit  3216 ) that the contact did not meet the predefined intensity criteria, enable display of a user interface for interacting with the set of words within the plurality of words on the display unit  3202  (e.g., with the display enabling unit  3212 ). 
     In some embodiments, correcting the misspelled word in response to the gesture includes displaying a first correction for the misspelled word; and the processing unit  3206  is configured to: after detecting the gesture: while a focus selector is at a location corresponding to the first correction for the misspelled word, detect a second gesture that includes a contact on the touch-sensitive surface unit  3204  (e.g., with the detecting unit  3208 ); and in response to detecting the second gesture: in accordance with a determination that the contact in the second gesture met the predefined intensity criteria, enable display of a second correction for the misspelled word, wherein the second correction is different from the first correction (e.g., with the display enabling unit  3212 ); and in accordance with a determination that the contact in the second gesture did not meet the predefined intensity criteria, place a text cursor within the first correction for the misspelled word (e.g., with the placing unit  3220 ). 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 12A-12D  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 13 . For example, detection operation  3108 , correction operation  3132 , and displaying operation  3140  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally utilizes or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIG. 1A   
     Editing a Field in a Sheet of an Electronic Document 
     Many electronic devices use graphical user interfaces to display electronic documents. In some embodiments, these documents can include sheets however switching between editing the electronic document and templates for the electronic document sometimes takes a large number of distinct inputs that can be confusing and inefficient for the user. For example, a spreadsheet document tracking financial data for a company optionally includes several sheets, or pages, with each sheet corresponding to a different fiscal quarter. Likewise, a presentation document, such as a document produced by KEYNOTE available from APPLE, INC can include multiple slides. In some embodiments described below, sheets within the document are linked to default properties of a template. For example, a title slide in a presentation document can be linked to default properties of fields within the title slide (e.g., a title field, sub-title, etc). In some embodiments, these default properties also control properties of fields (e.g., font, boldface, font size, location within the slide) within a new title slide created by a user. There is a need for a fast, efficient, convenient manner in which to determine whether to edit content of a field in a sheet or to edit default properties of the field in a template for the sheet. The embodiments described below provide a fast, efficient, convenient manner in which to determine whether to edit content of a field in a sheet or to edit default properties of the field in a template for the sheet based on an intensity of a contact while a focus selector is over the field. In particular, in some embodiments described below, a determination as to whether to edit content of a field in a sheet or to edit default properties of the field in a template for the sheet is made by a device based on an intensity of a contact, on the touch-sensitive surface, associated with the respective field in the respective sheet. 
       FIGS. 14A-14N  illustrate exemplary user interfaces for editing a field in a sheet of an electronic document in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in  FIGS. 15A-15C .  FIGS. 14A-14N  include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a respective intensity threshold (e.g., “IT D ”). In some embodiments, operations similar to those described below with reference to “IT D ” are performed with reference to a different intensity threshold (e.g., “IT L ”). 
     In some embodiments, the device is an electronic device with a separate display (e.g., display  450 ) and a separate touch-sensitive surface (e.g., touch-sensitive surface  451 ). In some embodiments, the device is portable multifunction device  100 , the display is touch-sensitive display system  112 , and the touch-sensitive surface includes tactile output generators  167  on the display ( FIG. 1A ). For convenience of explanation, the embodiments described with reference to  FIGS. 14A-14N and 15A-15C  will be discussed with reference to display  450  and a separate touch-sensitive surface  451 , however analogous operations are, optionally, performed on a device with a touch-sensitive display system  112  in response to detecting the contacts described in  FIGS. 14A-14N  on the touch-sensitive display system  112  while displaying the user interfaces shown in  FIGS. 14A-14N  on the touch-sensitive display system  112 ; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 , in place of cursor  5106 . 
       FIG. 14A  shows an electronic document  5104  that includes a respective slide  5101  and slide representations  5105  (e.g., thumbnail icons corresponding to associated slides). In this example, electronic document  5104  is a presentation document and slide  5101  is a sheet within the presentation document. Slide representations  5105 - 1  through  5105 - 4  correspond to slides within document  5104 . Slide representation  5105 - 1 , for example, corresponds to slide  5101 . Slide representation  5105 - 3  corresponds to a different slide based on the same template as slide  5101  (e.g., a title slide template). Slide representations  5105 - 2  and  5105 - 4  correspond to still different slides based on one or more different templates. Slide  5101  has a plurality of fields for entering content. For example, field  5103  is a title field and  5107  is a subtitle field. A user, for example a supervisor reviewing an employee&#39;s work, may wish to correct several stylistic and typographical issues within fields of slide  5101 . For example, the manager may want to correct the misspelling of the word “bellwether” (signified by the underlining of the word by a spell-checker) in subtitle field  5107  and italicize the content of subtitle field  5107  for emphasis. For convenience of explanation, in  FIGS. 14A-14N  reference numbers appended with hyphens and lower case letters (e.g., “ 5106 - a ” and “ 5106 - b ”) indicate similar elements at different position. 
     In  FIGS. 14A-14B , the device detects movement of contact  5108  across the touch-sensitive surface  451  while contact  5108  has an intensity between IT 0  and IT L  and in response to detecting movement of contact  5108 , the device moves the focus selector (e.g., cursor  5106 ) over subtitle field  5107 , as shown in  FIG. 14B . 
     In  FIGS. 14B-14C , the device detects a press input including an increase in intensity of contact  5108  from an intensity below IT L  to an intensity above IT L . In response to detecting the press input, the device enters a sheet editing mode and selects the text in subtitle field  5107  which can then be edited by the user. 
     In  FIG. 14D  the user has instructed the device to change a default property (font style) of a respective field (subtitle field  5107 ) to a custom property (italics) in a particular sheet (slide  5101 ). The default property for subtitle fields within title slides using the same template as slide  5101  in general, however, is still non-italicized. For example, in some embodiments, if the user were to produce a new slide using the title slide template that was used for slide  5101 , text in the subtitle field would not be italicized, because the default property of subtitle field  5107  has not been changed. 
     In  FIGS. 14E-14G , the device detects a press input including an increase in intensity of contact  5110  from an intensity below IT D  to an intensity above IT D . In response to detecting the press input, the device enters a template editing mode for editing template  5111  (shown in  FIG. 14G ).  FIG. 14F  illustrates an example of displaying an animated transition corresponding to ceasing to display the portion of the respective sheet and displaying a portion of the template according to some embodiments. In this example, slide  5101  is “peeled away” from the display, leaving the template  5111  underneath. In some embodiments, slide  5101  “slides away” towards the top or bottom of electronic document  5104 , template  5111  (shown in  FIG. 14G ) “slides over” slide  5101  from the top or bottom, and slide  5101  fades away (increases transparency) revealing template  5111  or “dissolves,” revealing template  5111 . In some embodiments, when the focus selector is over a particular field (e.g., field  5107  in  FIG. 14D ) in the sheet prior to displaying template  5111 , a corresponding field (e.g., subtitle default field  5117 ) in template  5111  is selected when the template  5111  is displayed. In some embodiments, the animation progresses in accordance with an intensity or a change in intensity of contact  5110  on the touch-sensitive surface. 
       FIG. 14G  illustrates an exemplary template editing mode for editing template  5111 . In some embodiments, slide representations  5105 - 1  and  5105 - 3  are highlighted because they are based on template  5111 . Slide representation  5105 - 2  and  5105 - 4  are not highlighted because they are based on a different template. In some embodiments, the template editing mode includes a template switching interface  5113 . Template switching interface  5113  contains at least one default template. For example, template switching interface  5113  in  FIG. 14G  includes default templates  5115 - 1 ,  5115 - 2  and  5115 - 3 . 
     In  FIGS. 14G-14H , the device detects movement of contact  5112  across the touch-sensitive surface  451  while contact  5112  has an intensity between IT 0  and IT L  and in response to detecting movement of contact  5112 , the device moves the focus selector (e.g., cursor  5106 ) from subtitle default field  5117  to fill palette  5119 , as shown in  FIG. 14H . 
     In  FIGS. 14H-14I , the device detects a press input including an increase in intensity of contact  5112  from an intensity below IT L  to an intensity above IT L  while subtitle default field  5117  is active and the focus selector (e.g., cursor  5106 ) is over fill palette  5119 . In response to detecting the press input, the device changes a fill property of subtitle default field  5117  (e.g., from a white fill to a gray fill). The same property is also changed in the respective subtitle fields of the slides corresponding to slide representations  5105 - 1  and  5105 - 3 . 
     In  FIGS. 14J-14K , the device detects a press input including an increase in intensity of contact  5114  from an intensity below IT L  to an intensity above IT L  while subtitle default field  5117  is active and the focus selector (e.g., cursor  5106 ) is over fill palette  5119 . In response to detecting the press input, the device changes a fill property of subtitle default field  5117  (e.g., from a white fill to a gray fill), as in the previous example. In the example shown in  FIG. 14J , however, the default fill property of field  5126  in the slide corresponding to slide representation  5105 - 3  was previously overridden (e.g., by a user changing the fill property of the field while the application was in a sheet editing mode) and the change in the default fill property of subtitle default field  5117  does not cause the fill property of field  5126  to change. 
     In  FIGS. 14L-14M , the device detects movement of contact  5116  across the touch-sensitive surface  451  while contact  5116  has an intensity between IT 0  and IT L  and in response to detecting movement of contact  5116 , the device moves the focus selector (e.g., cursor  5106 ) from fill palette  5119  to template switching interface  5113 , as shown in  FIG. 14M . 
     In  FIGS. 14M-14N , the device detects a press input including an increase in intensity of contact  5116  from an intensity below IT L  to an intensity above IT L  while the focus selector (e.g., cursor  5106 ) is over template switching interface  5113 . In response to detecting the press input, the properties of template  5111  are replaced with properties of the default template  5115 - 2 . For example, position properties of the title and subtitle default fields are changed, e.g., from center justified to left justified. 
       FIGS. 15A-15C  are flow diagrams illustrating a method  5200  of editing a field in a sheet of an electronic document in accordance with some embodiments. The method  5200  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  5200  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  5200  provides an intuitive way to edit a field in a sheet of an electronic document. The method reduces the cognitive burden on a user when editing a field in a sheet of an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to editing a field in a sheet of an electronic document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 5202 ) a respective sheet (e.g., slide  5101 ) of an electronic document having a plurality of sheets. The respective sheet includes a plurality of fields (e.g., title field  5103  and subtitle field  5107 ,  FIG. 14A ) for inserting content. The respective sheet is linked to a template that controls default properties of a respective field in the plurality of fields (e.g., template  5111  in  FIGS. 14G-14N ). In some embodiments, the electronic document is a presentation document ( 5204 ) and the respective sheet is a slide in the presentation document. In some embodiments, the electronic document is a word processing document ( 5206 ) and the respective sheet is a page in the word processing document. In some embodiments, the default properties include ( 5208 ) one or more of text typeface, text size, text color, border color, border style, border width, fill color, fill style, opacity, paragraph spacing, line spacing, and a text wrapping property. In some embodiments, a plurality of sheets in the electronic document, including the respective sheet, are based ( 5210 ) on the template, for example, the slides corresponding to slide representations  5105 - 1  and  5105 - 3  in  FIG. 14G . In some embodiments, the device also displays (e.g., on display  450  in  FIGS. 14A-14N ) representations of two or more sheets in the electronic document, for example, slide representations  5105 - 1  through  5105 - 4 . 
     The device detects ( 5212 ) a gesture that includes a press input from a contact (e.g., a finger contact) on the touch-sensitive surface while the focus selector is over the respective field (e.g., the increase in intensity of contact  5108  shown in  FIGS. 14B-14C , or the increase in intensity of contact  5110  shown in  FIGS. 14E-14F ). In response to detecting the gesture on the touch-sensitive surface, the device performs ( 5214 ) one or more of operations  5216 - 5234 . 
     The device determines whether the press input had a maximum intensity during the gesture that was above a respective intensity threshold (e.g., IT D ). In accordance with a determination that the press input reached an intensity during the gesture that was above the respective intensity threshold (e.g., “IT D ”), the device enters ( 5216 ) a template editing mode for editing default properties of the respective field in the template. For example, in  FIG. 14F , contact  5108  has a maximum intensity that is above IT D  and thus the device enters a template editing mode, as shown in  FIGS. 14G-14N . In some embodiments, entering the template editing mode includes ( 5218 ) ceasing to display at least a portion of the respective sheet, displaying at least a portion of the template and displaying an animated transition corresponding to ceasing to display the portion of the respective sheet and displaying the portion of the template. For example, an animation is displayed of the respective sheet peeling back to display the template underneath or display the template appearing on top of the respective sheet (e.g., as shown in  FIG. 14F ). 
     In some embodiments, to the device displays, while in template editing mode, visual indicia that particular sheets in the plurality of sheets are based on the template. For example, in some embodiments, prior to detecting the gesture on the touch-sensitive surface, the device display representations of a plurality of sheets in the electronic document and while in the template editing mode, the device highlights ( 5220 ) representations of a subset of the plurality of sheets in the electronic document, the subset comprising sheets that are based on the template (e.g., as illustrated in  FIGS. 14G-14N  where sheets  5105 - 1  and  5105 - 3  are based on template  5111 ). In some embodiments, respective sheet representations of the subset of sheets based on the template are altered to give the appearance of highlighting by altering the border or body of a given sheet representation (e.g., the border of the representations are changed to a bright color to give the impression that those sheets are “glowing” or “active”). 
     In some embodiments, while in the template editing mode, the device displays ( 5222 ) a template switching interface that includes a representation of the template for the respective sheet, and a representation of at least one different template, where selecting a representation of a respective template in the template switching interface selects the respective template for use as a template for the respective sheet (e.g., in response to detecting selection of a template from the template switching interface, the device selects a different template for the respective sheet). An illustrative example of a template switching interface  5113  is discussed in greater detail with reference to  FIGS. 14L-14N . 
     In some embodiments, a plurality of sheets in the electronic document, including the respective sheet, are based ( 5224 ) on the template, and while in the template editing mode, the device detects ( 5226 ), an input that corresponds to a change in a default property of the respective field in the template (e.g., a press input corresponding to an increase in intensity of contact  5112  in  FIGS. 14H-14I ). In response to detection of the input, the device changes ( 5228 ) the default property of the respective field in the template and changes the default property of fields corresponding to the respective field in the template in the plurality of sheets in the electronic document that are based on the template (e.g., in  FIG. 14I , default properties in fields corresponding to representations of sheets  5105 - 1  and  5105 - 3  are changed from a white fill to a gray fill). In some embodiments, changing the default property of a field in a particular sheet where the default property has not been overridden changes the field in the particular sheet. For example, if the default font color in title field within a slide template (e.g., template  5111  in  FIGS. 14G-14N ) is changed from red to green and, furthermore, the font color for the particular instance of the title field that is based on the template (e.g., title field  5103  in slide  5101 ) has not been overridden with a custom font color, the change from red to green is effected in the particular instance of the title field as well (e.g., title field  5103  in slide  5101 ). In some embodiments, changing the default property of a field in a particular sheet where the default property has been overridden by a custom property does not override or remove the custom property in the particular sheet. For example, if the default text color for text in a text box is red but in a particular sheet, a user has changed the color of the text to blue, changing the default text color for text in the text box from red to green will not affect the color of the text in the text box in the particular sheet, as the user has already overridden the default text color value for that text box on the particular sheet. 
     As described above, the device determines whether the press input had a maximum intensity during the gesture that was above a respective intensity threshold. In accordance with a determination that the press input had a maximum intensity during the gesture that was below the respective intensity threshold (e.g., “IT D ”), the device enters ( 5230 ) a sheet editing mode for editing content of the respective field in the respective sheet. In some embodiments, while in the sheet editing mode, the device detects ( 5232 ) an input that corresponds to a change in a respective property of the respective field from a default property to a custom property. In response to detecting the input, the device changes ( 5234 ) the respective property in the respective field in the respective sheet to the custom property without changing the default property in the respective field in the template (e.g., the default property in fields corresponding to the respective field in the template in the plurality of sheets in the electronic document are also not changed). For example, when the text in subtitle field  5107  is italicized in  FIG. 14D  the other subtitle fields in other sheets that use the same template are, optionally, not italicized. 
     It should be understood that the particular order in which the operations in  FIGS. 15A-15C  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method  5200  described above with respect to  FIGS. 15A-15C . For example, the contacts, gestures, user interface objects, intensity thresholds, focus selectors, animations described above with reference to method  600  optionally have one or more of the characteristics of the contacts, gestures, user interface objects intensity thresholds, focus selectors, animations described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here. 
     In accordance with some embodiments,  FIG. 16  shows a functional block diagram of an electronic device  5300  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 16  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG. 16 , an electronic device  5300  includes a display unit  5302  configured to display a respective sheet of an electronic document having a plurality of sheets, where the respective sheet includes a plurality of fields for inserting content and the respective sheet is linked to a template that controls default properties of a respective field of the plurality of fields; a touch-sensitive surface unit  5304  configured to receive contacts; one or more sensor units  5305  configured to detect intensity of contacts with the touch-sensitive surface unit  5304 ; and a processing unit  5306  coupled to the display unit  5302 , the touch-sensitive surface unit  5304 , and the sensor units  5305 . In some embodiments, the processing unit  5306  includes a detecting unit  5308 , a sheet editing unit  5310 , a template editing unit  5312 , a display enabling unit  5314 , a highlighting unit  5316  and a changing unit  5318 . 
     The processing unit  5306  is configured to, while a focus selector is over the respective field, detect a gesture that includes a press input from a contact on the touch-sensitive surface unit (e.g., with the detecting unit  5308 ), and, in response to detecting the gesture on the touch-sensitive surface unit  5304 , the processing unit  5306  is configured to, in accordance with a determination that the press input had a maximum intensity during the gesture that was below a respective intensity threshold, enter a sheet editing mode for editing content of the respective field in the respective sheet (e.g., with the sheet editing unit  5310 ), and in accordance with a determination that the press input reached an intensity during the gesture that was above the respective intensity threshold, enter a template editing mode for editing default properties of the respective field in the template (e.g., with the template editing unit  5312 ). 
     In some embodiments, the electronic document is a presentation document and the respective sheet is a slide in the presentation document. 
     In some embodiments, the electronic document is a word processing document and the respective sheet is a page in the word processing document. 
     In some embodiments, the default properties include one or more of: text typeface, text size, text color, border color, border style, border width, fill color, fill style, opacity, paragraph spacing, line spacing, and a text wrapping property. 
     In some embodiments, the processing unit  5306  is configured to: prior to detecting the gesture on the touch-sensitive surface unit, enable display of representations of two or more sheets in the electronic document (e.g., with the display enabling unit  5314 ); and while in the template editing mode, highlight representations of a subset of the plurality of sheets in the electronic document (e.g., with the highlighting unit  5316 ), the subset comprising sheets that are based on the template. 
     In some embodiments, entering the template editing mode includes: ceasing to display at least a portion of the respective sheet; enabling display of at least a portion of the template (e.g., with the display enabling unit  5314 ); and enabling display of an animated transition corresponding to ceasing to display the portion of the respective sheet and displaying the portion of the template (e.g., with the display enabling unit  5314 ). 
     In some embodiments, the processing unit  5306  is configured to, while in the template editing mode, enable display of a template switching interface that includes: a representation of the template for the respective sheet; and a representation of a different template, where selecting a representation of a respective template in the template switching interface causes the processing unit  5306  to select the respective template for use as a template for the respective sheet. 
     In some embodiments, two or more sheets in the electronic document, including the respective sheet, are based on the template; and the processing unit  5306  is configured to, while in the template editing mode: detect an input that corresponds to a change in a default property of the respective field in the template (e.g., with the detecting unit  5308 ); and in response to detecting the input: change the default property of the respective field in the template (e.g., with the changing unit  5318 ); and change the default property of fields corresponding to the respective field in the template in the two or more sheets in the electronic document that are based on the template (e.g., with the changing unit  5318 ). 
     In some embodiments, the processing unit  5306  is configured to, while in the sheet editing mode: detect an input (e.g., with the detecting unit  5308 ) that corresponds to a change in a respective property of the respective field from a default property to a custom property; and in response to detecting the input, change (e.g., with the changing unit  5318 ) the respective property in the respective field in the respective sheet to the custom property without changing the default property in the respective field in the template. 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 15A-15C  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 16 . For example, detection operation  5212 , template editing mode entering operation  5216 , and sheet editing mode entering operation  5230  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally utilizes or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in  FIGS. 1A-1B . 
     Changing Text Wrapping Properties 
     Many electronic devices use graphical user interfaces to display electronic documents. These documents can include different types of objects, such as text and images, that are displayed with relationships relative to one another. For instance, the z-layer order of two images determines which of the images will be displayed on top if the images are position to overlap with one another. Text wrapping properties, more specifically, determine how text is displayed relative to user interface objects. Types of user interface objects include graphical objects such as images or icons, text boxes, and other objects that are displayed within an electronic document. There is often a need to change text wrapping properties in a fast, efficient, and convenient way however changing the text wrapping properties of a user interface object sometimes takes a large number of distinct inputs that can be confusing and inefficient for the user. The embodiments described below provide methods and user interfaces for changing text wrapping properties of a user interface objects in a fast, efficient, and convenient way based on an intensity of a contact while a focus selector is over the user interface object. For example, when a device has sensors that can detect the intensity of a contact with a touch-sensitive surface, the device can change text wrapping properties of an object in accordance with changes in intensity of a contact on the touch-sensitive surface. This method streamlines the process of changing text wrapping properties of an object by navigating through menus or memorizing keyboard shortcuts, thereby eliminating the need for extra, separate steps to change text wrapping properties of an object. 
       FIG. 17A-17K  illustrate an exemplary user interfaces for changing the text wrapping properties of a user interface object in accordance with some embodiments. The user interfaces in these figures are used to illustrate processes described below, including the processes described with reference to  FIGS. 18A-18B .  FIGS. 17A-17K  include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a predefined activation threshold (e.g., “IT D ”). In some embodiments, operations similar to those described below with reference to IT D  are performed with reference to a different intensity threshold (e.g., “IT L ”). 
       FIGS. 17A-17K  show an example of a display  450  and a touch-sensitive surface  451  of an electronic device (e.g., electronic device  300 ,  FIG. 3  or portable multifunction device  100 ,  FIG. 1A ). The touch-sensitive surface  451  includes a touch-sensitive surface with one or more contact intensity sensors  359  ( FIG. 3 ). The display  450  displays an electronic document  6300 . 
     In some embodiments, the device is an electronic device with a separate display (e.g., display  450 ) and a separate touch-sensitive surface (e.g., touch-sensitive surface  451 ). In some embodiments, the device is portable multifunction device  100 , the display is touch-sensitive display system  112 , and the touch-sensitive surface includes tactile output generators  167  on the display ( FIG. 1A ). For convenience of explanation, the embodiments described with reference to  FIGS. 17A-17K and 18A-18B  will be discussed with reference to display  450  and a separate touch-sensitive surface  451 , however analogous operations are, optionally, performed on a device with a touch-sensitive display system  112  in response to detecting the contacts described in  FIGS. 17A-17K  on the touch-sensitive display system  112  while displaying the user interfaces shown in  FIGS. 17A-17K  on the touch-sensitive display system  112 ; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system  112 , in place of cursor  6306 . 
     In accordance with some embodiments, a method is performed to change the text wrapping properties of a user interface object  6302  in an electronic document displayed by an electronic device. In some embodiments, the displayed electronic document includes text  6304  as well as one or more user interface objects  6302 . Text  6304  is displayed proximate to a user interface object  6302  according to a first set of text wrapping rules. Here, text that is “proximate” to a user interface object includes text that overlaps the user interface object  6302 , text that is overlapped by the user interface object  6302 , text that is laterally adjacent to the user interface object  6302 , and text that surrounds the user interface object  6302 . In some embodiments, text wrapping properties of user interface object  6302  indicate, for example, that a paragraph of text proximate to an image in a word processing document is to be displayed under the image (e.g., in a z-layer order), laterally adjacent to the image (e.g., surrounding the image, such that the user interface object is placed within the text), or on top of the image (e.g., in a z-layer order), as shown in  FIGS. 17A-17C , respectively. Stated another way, a current value of the text wrapping properties of user interface object  6302  indicates how the paragraph of text proximate to the image is to be displayed. 
     In some embodiments, as shown in  FIGS. 17A-17K , the user interface also includes a displayed representation of a focus selector  6306 , responsive to gestures (e.g., press inputs) on touch-sensitive surface  451 , for performing operations such as selecting a user interface object  6302  and placing text cursors (e.g.,  6314  in  FIG. 17K ) within text  6304 . In some instances, a displayed representation of the focus selector  6306  is a cursor with a position on the display  450  in accordance with press inputs from touch-sensitive surface  451 . Alternatively, in some embodiments a representation of the focus selector is not displayed. For example, in embodiments using a touch-sensitive display system, the position of the focus selector corresponds to the location on the display of the press input. Further, the focus selector is herein defined to be “over” a user interface object when the position of the focus selector corresponds to the location on the display of the user interface object. 
       FIGS. 17A-17C  illustrate changing text wrapping properties of user interface object  6302  through a plurality of values in accordance with changes in an intensity of contact  6310  through a plurality of values. For example, in  FIG. 17A , user interface object  6302  is displayed on top of text  6304  while the intensity of contact  6310  is below a first intensity threshold (e.g., “IT L ”) and a second intensity threshold (e.g., “IT D ”). In response to detecting an increase in intensity of contact  6310  above the first intensity threshold while the focus selector (e.g., cursor  6306 ) is over the user interface object  6302 , the device changes the text wrapping properties of user interface object  6302 , so that user interface object  6302  is displayed within text  6304 , as illustrated in  FIG. 17B . In response to detecting a further increase in intensity of contact  6310  above the second intensity threshold while the focus selector (e.g., cursor  6306 ) is over the user interface object  6302 , the device changes the text wrapping properties of user interface object  6302 , so that user interface object  6302  is displayed underneath text  6304 , as illustrated in  FIG. 17C . For ease of explanation, a press input performed by a contact (e.g., contact  6310  in  FIGS. 17A-17C ) corresponding to a contact with an intensity above a predefined threshold is sometimes herein referred to as a press input with an intensity above a predefined threshold. 
       FIGS. 17D-17E  illustrate an example of a change in the text wrapping properties from a first text wrapping property (e.g., “on top of text”) to a second text wrapping property (e.g., “within text”) when a press input, corresponding to a contact  6312  with an intensity above a predefined threshold (e.g., “IT D ”), is detected while the focus selector (e.g., cursor  6306 ) is over the user interface object  6302 . In particular, in  FIG. 17D , contact  6312  has an intensity below IT D  and in  FIG. 17E , contact  6312  has an intensity above IT D . 
       FIGS. 17F-17G  illustrate an example of a change in the text wrapping properties from a first text wrapping property (e.g., “within text”) to a second text wrapping property (e.g., “underneath text”) when a press input, corresponding to a contact  6314  with an intensity above a predefined threshold (e.g., “IT D ”), is detected while the focus selector (e.g., cursor  6306 ) is over the user interface object  6302 . In particular, in  FIG. 17F , contact  6314  has an intensity below IT D  and in  FIG. 17G , contact  6314  has an intensity above IT D . 
       FIGS. 17H-17I  illustrate an example of a change in the text wrapping properties from a first text wrapping property (e.g., “underneath text”) to a second text wrapping property (e.g., “on top of text”) when a press input, corresponding to a contact  6316  with an intensity above a predefined threshold (e.g., “IT D ”), is detected while the focus selector (e.g., cursor  6306 ) is over the user interface object  6302 . In particular, in  FIG. 17H , contact  6316  has an intensity below IT D  and in  FIG. 17I , contact  6316  has an intensity above IT D . 
       FIGS. 17J-17K  illustrate examples of performing operations other than changing text wrapping properties of a user interface object when a contact has an intensity below the predefined activation threshold (e.g., “IT D ”). According to some embodiments, a subsequent gesture, corresponding to a subsequent contact having intensity below the aforementioned predefined activation threshold, (e.g., a subsequent press input corresponding to contact  6318  or contact  6320 , which has an intensity between IT L  and IT D ) is detected on the touch-sensitive surface  451 . In some circumstances (e.g., when the focus selector  6306  is positioned over a respective user interface object, such as user interface object  6302  in  FIG. 17J ), in response to detecting a subsequent gesture (e.g., a press input corresponding to an increase of intensity of contact  6318  above IT L , as shown in  FIG. 17J ), the respective user interface object is selected, as shown in  FIG. 17J . In some other circumstances (e.g. when the focus selector  6306  is position over a respective paragraph of text as shown in  FIG. 17K ), in response to detecting a subsequent gesture (e.g., a press input corresponding to an increase of intensity of contact  6320  above IT L , as shown in  FIG. 17K ), a text cursor  6314  is placed in the respective paragraph of text, as shown in  FIG. 17K . In some instances, the text cursor  6314  is placed at a location determined by the location of the visual representation of the focus selector over the text (e.g. the text cursor  6314  is placed at the location of the focus selector  6306  on the display in  FIG. 17K ). It should be appreciated that, in some embodiments, other functions are associated with the subsequent gesture, such as the appearance of rotation handles or a displaying a copy/cut/paste interface to the user. 
       FIG. 18A-18B  are flow diagrams illustrating a method  6400  of changing the text wrapping properties of a user interface object in accordance with some embodiments. The method  6400  is performed at an electronic device (e.g. device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1A ) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  6400  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  6400  provides an intuitive way to change text wrapping properties of a user interface object. The method reduces the cognitive burden on a user when changing text wrapping properties of a user interface object, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to change text wrapping properties of a user interface object faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays ( 6402 ) a document (e.g., document  6300  in  FIG. 17A ) that includes text (e.g.,  6304  in  FIG. 17A ) and a user interface object (e.g., object  6302  in  FIG. 17A ) on the display (e.g., a graphical object such as an image or an icon, or a text box or other object that is to be displayed in conjunction with the text of the document). Text proximate to the user interface object is initially displayed in accordance with first text wrapping properties of the user interface object. Here, text that is “proximate” to a user interface object includes text that overlaps the user interface object, text that is overlapped by the user interface object, text that is laterally adjacent to the user interface object, and text that surrounds the user interface object. For example, a paragraph of text proximate to an image in a word processing document is, optionally, displayed over the image (e.g., in a z-layer order) as shown in  FIG. 17A , under the image (e.g., in a z-layer order) as shown in  FIG. 17B , laterally adjacent to the image, or above the image as shown in  FIG. 17C . 
     In some embodiments, shown in  FIG. 17D , the first text wrapping properties indicate that the user interface object (e.g., object  6302  in  FIG. 17D ) is to be displayed on top of the text (e.g., text  6304  in  FIG. 17D ). Alternatively, as shown in  FIG. 17F , the first text wrapping properties indicate that the user interface object (e.g., object  6302  in  FIG. 17F ) is to be displayed within the text (e.g., text  6304  in  FIG. 17F ). Still another alternative, shown in  FIG. 17H , is that the first text wrapping properties indicate that the user interface object (e.g., object  6302  in  FIG. 17H ) is to be displayed underneath the text (e.g.,  6304  in  FIG. 17H ). 
     While the focus selector is over the user interface object, the device detects ( 6404 ) a respective press input from a contact (e.g., a finger contact) on the touch-sensitive surface with an intensity above a predefined threshold (e.g., an increase in intensity of contact  6310  in  FIGS. 17B-17C , contact  6312  in  FIG. 17E , contact  6314  in  FIG. 17G , or contact  6316  in  FIG. 17I  above IT D ). In some embodiments, the contact is a finger contact. 
     In response to the detection of the respective press input, the device changes ( 6406 ) the text wrapping properties of the user interface object to second text wrapping properties, distinct from the first text wrapping properties and the device displays text proximate to the user interface object in accordance with the second text wrapping properties of the user interface object. In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed ( 6408 ) on top of the text (e.g., the user interface object is displayed so that it overlays at least a portion of a block of text, as illustrated in  FIG. 17D ); and the second text wrapping properties indicate that the user interface object is to be displayed within the text (e.g., text is wrapped around the user interface object, as illustrated in  FIG. 17E  when contact  6312  increases above IT D ). In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed ( 6410 ) within the text (e.g., text is wrapped around the user interface object, as illustrated in  FIG. 17F ); and the second text wrapping properties indicate that the user interface object is to be displayed underneath the text (e.g., the text is displayed so that it overlays the user interface object, as illustrated in  FIG. 17G  when contact  6314  increases above IT D ). In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed ( 6412 ) on top of the text (e.g., the user interface object is displayed so that it overlays at least a portion of a block of text, as illustrated in  FIG. 17A ); and the second text wrapping properties indicate that the user interface object is to be displayed underneath the text (e.g., the text is displayed so that it overlays the user interface object, as illustrated in  FIG. 17C  when contact  6310  increases above IT D ). In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed ( 6414 ) underneath the text (e.g., the text is displayed so that it overlays the user interface object, as illustrated in  FIG. 17F ); and the second text wrapping properties indicate that the user interface object is to be displayed on top of the text (e.g., the user interface object is displayed so that it overlays at least a portion of a block of text, as illustrated in  FIG. 17G  when contact  6316  increases above IT D ). Thus, in some embodiments, if the user interface object is already at a “lowest” text wrapping level, a deep press on the object causes the object to spring back up to the “highest” text wrapping level. 
     In some embodiments, while the focus selector (e.g., cursor  6306  in  FIG. 17J ) is over the user interface object, the device detects ( 6416 ) a subsequent press input from a contact (e.g., a finger contact) on the touch-sensitive surface with intensity below the predefined activation threshold (e.g., an increase in intensity of contact  6318  in  FIG. 17J  above IT L ), and in response to detecting the subsequent press input, the device selects ( 6418 ) the user interface object. For example, in  FIG. 17J , user interface object  6302  is selected in response to the press input corresponding to the increase in intensity of contact  6318 . Thus, in the embodiment described above, if the respective press input has an intensity below the predefined activation threshold, the user interface object is selected in response to detecting the respective press input, instead of changing the text wrapping properties of the user interface object. In some embodiments, press inputs detected with a contact intensity below a predefined activation threshold can perform tasks commonly and intuitively associated with a low intensity press input, such as the selection of an object on a display. 
     In some embodiments, while the focus selector (e.g., cursor  6306  in  FIG. 17K ) is over the text, the device detects ( 6420 ) a subsequent press input from a contact (e.g. a finger contact) on the touch-sensitive surface with intensity below the predefined activation threshold (e.g., an increase in intensity of contact  6320  in  FIG. 17K  above IT L ); and in response to detecting the subsequent press input, the device places ( 6422 ) a cursor in the text at a location corresponding to the focus selector. For example, in  FIG. 17K , text cursor  6314  is placed in the text in response to the press input corresponding to the increase in intensity of contact  6320 . Thus, in the embodiment described above, if the respective press input has an intensity below the predefined activation threshold, a text cursor is inserted into the text in response to detecting the respective press input, instead of changing the text wrapping properties of the user interface object. In some embodiments, press inputs detected with a contact intensity below a predefined activation threshold can perform tasks commonly and intuitively associated with a low intensity press input, such as the placement of a cursor within text. 
     It should be understood that the particular order in which the operations in  FIGS. 18A-18B  have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method  6400  described above with respect to  FIGS. 18A-18B . For example, the contacts, user interface objects, intensity thresholds, and focus selectors described above with reference to method  6400  optionally have one or more of the characteristics of the contacts, user interface objects, intensity thresholds, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here. 
     In accordance with some embodiments,  FIG. 19  shows a functional block diagram of an electronic device  6500  configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in  FIG. 19  are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG. 19 , an electronic device  6500  includes a display unit  6502  configured to display a document, where the document has at least text and a user interface object; a touch-sensitive surface unit  6504  configured to receive contacts; one or more sensor units  6505  configured to detect intensity of contacts with the touch-sensitive surface unit  6504 ; and a processing unit  6506  coupled to the display unit  6502 , the touch-sensitive surface unit  6504 , and the sensor units  6505 . In some embodiments, the processing unit  6506  includes a detecting unit  6508 , a changing unit  6510 , a selecting unit  6512 , a display enabling unit  6514 , and a cursor placing unit  6516 . 
     The processing unit  6506  is configured to enable display of a document that includes text and a user interface object on the display (e.g., with the display enabling unit  6514 ), where text proximate to the user interface object is displayed in accordance with first text wrapping properties of the user interface object and while a focus selector is over the user interface object, detect the respective press input from the contact on the touch-sensitive surface unit  6504  with intensity above a predefined activation threshold (e.g., with the detecting unit  6508 ). The processing unit  6506  is further configured to, in response to detection of the respective press input, change the text wrapping properties of the user interface object to second text wrapping properties (e.g., with the changing unit  6510 ), distinct from the first text wrapping properties, and enable display of text proximate to the user interface object (e.g., with the display enabling unit  6514 ) in accordance with the second text wrapping properties of the user interface object. 
     In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed on top of the text; and the second text wrapping properties indicate that the user interface object is to be displayed within the text. 
     In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed within the text; and the second text wrapping properties indicate that the user interface object is to be displayed underneath the text. 
     In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed on top the text; the second text wrapping properties indicate that the user interface object is to be displayed underneath the text. 
     In some embodiments, the first text wrapping properties indicate that the user interface object is to be displayed underneath the text; and the second text wrapping properties indicate that the user interface object is to be displayed on top of the text. 
     In some embodiments, the touch-sensitive surface unit  6504  is further configured to receive a subsequent press input from a contact on the touch-sensitive surface unit  6504  with intensity below the predefined activation threshold. 
     In some embodiments, the processing unit  6506  is further configured to: while the focus selector is over the user interface object, detect the subsequent press input from the contact on the touch-sensitive surface unit  6504  with intensity below the predefined activation threshold (e.g., with the detecting unit  6508 ); and in response to the detection of the subsequent press input, select the user interface object (e.g., with the selecting unit  6512 ). 
     In some embodiments, the processing unit  6506  is further configured to, while the focus selector is over the text, detect the subsequent press input from the contact on the touch-sensitive surface unit  6504  with intensity below the predefined activation threshold (e.g., with the detecting unit  6508 ); and in response to the detection of the subsequent press input, place a cursor in the text at a location corresponding to the focus selector (e.g., with the cursor placing unit  6516 ). 
     The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to  FIGS. 1A and 3 ) or application specific chips. 
     The operations described above with reference to  FIGS. 17A-17K, 18A-18B  are, optionally, implemented by components depicted in  FIGS. 1A-1B  or  FIG. 19 . For example, display operation  6402 , detection operation  6404 , and text wrapping property changing operation  6406  are, optionally, implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  optionally utilizes or calls data updater  176  or object updater  177  to update the application internal state  192 . In some embodiments, event handler  190  accesses a respective GUI updater  178  to update what is displayed by the application.
