     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 using a predictive keyboard. 
     BACKGROUND 
     An on-screen keyboard enables a user to type characters into a text field using a touch-sensitive surface as an input device for a computer or other electronic computing device. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Sometimes, an on-screen keyboard is used in conjunction with a predictive text system, which predicts character strings that the user might want to type. 
     SUMMARY 
     A combination of an on-screen keyboard and a predictive text system (a “predictive keyboard”) displays one or more predicted character strings. If the user taps a predicted character string, then that character string is inserted into the text field. This functionality enables the user to avoid typing the entire character string. 
     Some methods for using a predictive keyboard are inefficient. For example, requiring the user to move the contact point away from the on-screen keyboard region in order to tap the desired predicted character string region is inconvenient for the user, wastes the user&#39;s time, and wastes the device&#39;s energy (which is particularly important in battery-operated devices). Also, as a user types, the displayed predicted character strings can change, distracting the user and increasing the user&#39;s cognitive burden. This reduces the user&#39;s efficiency when using the device. As a result, the user requires more time to perform a task, which wastes the user&#39;s time and wastes the device&#39;s energy. 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and user interfaces for using a predictive keyboard. Such methods and interfaces optionally complement or replace conventional methods for using a predictive keyboard. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges. 
     The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In accordance with some embodiments, a method is performed at an electronic device with a display and a touch-sensitive surface. The method includes displaying a suggestion region above an on-screen keyboard, the suggestion region including multiple suggested character strings. The method also includes detecting a gesture that begins within a predefined key of the on-screen keyboard. The method also includes responsive to detecting the gesture: in accordance with a determination that the gesture ends within the predefined key, inserting a first character string into a text field; and in accordance with a determination that the gesture ends outside of the predefined key, inserting a second character string into the text field, wherein the second character string is different from the first character string. 
     In accordance with some embodiments, an electronic device includes a display unit configured to display a user interface with a suggestion region above an on-screen keyboard, the suggestion region including multiple suggested character strings, a touch-sensitive surface unit configured to receive user contacts, and a processing unit coupled to the display unit and the touch-sensitive unit. The processing unit is configured to detect a gesture that begins within a predefined key of the on-screen keyboard. The processing unit is further configured to, responsive to detecting the gesture: in accordance with a determination that the gesture ends within the predefined key, insert a first character string into a text field; and in accordance with a determination that the gesture ends outside of the predefined key, insert a second character string into the text field, wherein the second character string is different from the first character string. 
     In accordance with some embodiments, a method is performed at an electronic device with a display and a touch-sensitive surface. The method includes receiving one or more entered characters. The method further includes, after receiving the one or more entered characters, displaying a suggestion region that includes a set of one or more suggestions including one or more character strings that start with the one or more entered characters. The method further includes, while displaying the set of one or more suggestions, receiving one or more additional entered characters. The method further includes, responsive to receiving the one or more additional entered characters, updating the set of suggestions, wherein the updating comprises: changing a first suggestion in the set of one or more suggestions from a first character string to a second character string, comprising, while maintaining display of a first portion of the first character string: ceasing to display a second portion of the first character string that is incompatible with the one or more additional entered characters; adding the one or more additional entered characters to the first portion of the first character string; and adding a first set of one or more predicted characters to the first portion of the first character string to display the second character string. 
     In accordance with some embodiments, an electronic device includes a display unit configured to display a user interface with a suggestion region that includes a set of one or more suggestions including one or more character strings that start with one or more entered characters, a touch-sensitive surface unit configured to receive user contacts, and a processing unit coupled to the display unit and the touch-sensitive unit. The processing unit is configured to, while displaying the set of one or more suggestions, receive one or more additional entered characters. The processing unit is further configured to, responsive to receiving the one or more additional entered characters, update the set of suggestions, wherein the updating comprises: changing a first suggestion in the set of one or more suggestions from a first character string to a second character string, comprising, while maintaining display of a first portion of the first character string: ceasing to display a second portion of the first character string that is incompatible with the one or more additional entered characters; adding the one or more additional entered characters to the first portion of the first character string; and adding a first set of one or more predicted characters to the first portion of the first character string to display the second character string. 
     In accordance with some embodiments, a method is performed at an electronic device with a display and a touch-sensitive surface. The method includes displaying a set of one or more suggestions including one or more character strings that are suggested replacements for a first set of one or more entered characters. The method further includes while displaying the set of suggestions, receiving one or more additional entered characters. The method further includes after receiving the additional entered characters, updating the set of suggestions based on an updated set of entered characters that includes the first set of entered characters and the additional entered characters. The updating comprises changing a first suggestion in the set of suggestions from a first character string that is a suggested replacement for the first set of entered characters to a second character string that is a suggested replacement for the updated set of entered characters. The changing comprises determining a maintained portion of the first character string that is identical to a corresponding portion of the second character string, determining an inserted portion of the second character string that is inserted relative to the maintained portion of the first character string (the inserted portion having a sequence of characters), and while displaying the maintained portion of the first character string, sequentially displaying the characters of the inserted portion of the second character string after the maintained portion of the first character string.

     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.  1 A 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.

The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), 
     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 ). In some embodiments, at least one contact intensity 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 proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  is coupled to input controller  160  in 1/0 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 . Alternately, accelerometer  168  is, optionally, coupled to an input controller  160  in I/O subsystem  106 . In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device  100  optionally includes, in addition to accelerometer(s)  168 , a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  100 .

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 (e.g., different motions, timings, and/or intensities of detected contacts). 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 .

     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 - 13 ,  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  176  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 , headset 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  is, 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  359 ) for detecting intensity of contacts on touch-sensitive surface  451  and/or one or more tactile output generators  357  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). 
     User Interfaces and Associated Processes 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device with a display and a touch-sensitive surface, such as device  300  or portable multifunction device  100 . 
       FIGS. 5A-5O  illustrate exemplary user interfaces for inserting a character string into a text field in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the process in  FIG. 7 . 
       FIGS. 5A-5O  illustrate user interface  500 , which can be displayed by, e.g., multifunction device  100 . User interface  500  includes message region  502 , on-screen keyboard region  504 , and suggestion region  506 . Message region  502  includes text field  508  and cursor  510 . On-screen keyboard region  504  includes space bar  512 . Suggestion region  506  includes multiple suggested character strings  514 A,  514 B,  514 C (collectively, “suggested character strings  514 ”). In some embodiments, one or more of the multiple suggested character strings  514  is a prediction of a character string being entered in text field  508 , an automatic correction of a character string being entered in text field  508 , an automatic completion of a character string being entered in text field  508 , or the character string that was just entered in text field  508 . In the illustrated embodiment in  FIG. 5A , suggestion region  506  is displayed above on-screen keyboard region  504 , and the multiple suggested character strings  514  are arranged horizontally within suggestion region  506 . 
     In  FIG. 5A , text field  508  displays “Producti”, which is a character string being entered in text field  508 . Cursor  510  is located immediately after the “Producti” character string, indicating that this string is still being entered. (If cursor  510  were separated from the string by a delimiter character, such as a space or a period, then this would indicate that the character string is complete.) The suggested character strings (“Producti”  514 A, “Production”  514 B, and “Productions”  514 C) are displayed in a left section, a middle section, and a right section of suggestion region  506 , respectively. In the illustrated embodiment in  FIG. 5A , suggested character string  514 A (“Producti”) is the character string that was just entered into text field  508 , suggested character string  514 B (“Production”) is a best prediction of the character string being entered into text field  508 , and suggested character string  514 C (“Productions”) is a second-best prediction of the character string being entered into text field  508 . 
       FIG. 5B  illustrates an embodiment where the user provides a gesture input including a tap on touch screen  112 . The location of the tap corresponds to the location of a suggested character string  514 . In the illustrated embodiment in  FIG. 5B , the location of the tap corresponds to the location of suggested character string  514 C (“Productions”). In response to detecting the tap&#39;s finger-down event, multifunction device  100  visually distinguishes the suggested character string  514  at that location from the other suggested character strings. In the illustrated embodiment in  FIG. 5B , multifunction device  100  visually distinguishes suggested character string  514 C from suggested character strings  514 A and  514 B by increasing the font size of suggested character string  514 C, changing the font style from plain to bold, and thickening the surrounding border. Other techniques for visually distinguishing a suggested character string  514  are possible. For example, multifunction device  100  can visually distinguish a suggested character string  514  by inverting the colors of the suggested character string  514  and its background (e.g., from black text on white background to white text on black background). 
     In response to detecting the tap&#39;s finger-up event, multifunction device  100  replaces the character string being entered in text field  508  (here, “Producti”) with the suggested character string  514  at the tapped location (here, suggested character string  514 C “Productions”). In some embodiments, multifunction device  100  also inserts a trailing space character into text field  508  after an inserted character string. This is shown in  FIG. 5C . In  FIG. 5C , text field  508  displays “Productions”, followed by a space character (not visible). Since cursor  510  is separated from “Productions” by a delimiter character (here, a space), this indicates that the character string is complete. Suggestion region  506  includes multiple suggested character strings  514  for insertion into text field  508  (after “Productions” and the delimiter). 
       FIG. 5D  illustrates an embodiment where the user provides a gesture input on touch screen  112  that begins within a predefined key within the on-screen keyboard region  504 . In the illustrated embodiment in  FIG. 5D , the predefined key is space bar  512 , and multifunction device  100  detects a contact on space bar  512 . However, other predefined keys and/or detected contacts are possible. In  FIG. 5D , the gesture includes movement of a contact from a first location (within the predefined key) to a second location (outside the predefined key). In other words, the movement extends beyond the predefined key. 
     In response to detecting movement of the contact beyond the predefined key, multifunction device  100  visually distinguishes a suggested character string  514  corresponding to the termination point of the movement (the second location of the contact) from the other suggested character strings  514 . This is shown in  FIG. 5E . A movement&#39;s termination point corresponds to a particular section of suggestion region  506  (e.g., the termination point is directly above, below, or within a particular section of suggestion region  506 ). The suggested character string  514  that is displayed within that particular section corresponds to the termination point. In the illustrated embodiment in  FIG. 5E , the termination point of the movement is directly below (and, therefore, corresponds to) the section in which suggested character string  514 C (“Productions”) is displayed. 
     The suggested character string  514  that corresponds to the termination point of the movement can be visually distinguished using various techniques, as described above with reference to  FIG. 5B . In some embodiments, multifunction device  100  visually distinguishes the suggested character string  514  corresponding to the termination point of the movement by increasing the height of the section of suggestion region  506  that includes this suggested character string. This is shown in  FIG. 5M , where the termination point of the movement is directly below (and, therefore, corresponds to) the section in which the “Everybody” suggested character string  514  is displayed. In the illustrated embodiment in  FIG. 5M , the “Everybody” suggested character string  514  is visually distinguished by increasing the height of the section of suggestion region  506  that includes this suggested character string. 
     In some embodiments, visually distinguishing the suggested character string  514  includes changing a color, contrast, brightness, line width, or other visual property of the suggested character string or a section of suggestion region  506  that encompasses the suggested character string. In some embodiments, the amount of visual emphasis of the suggested character string  514  increases as the contact moves farther away from the predefined key. For example, the section of suggestion region  506  that includes the suggested character string  514  gets taller and/or darker as the contact moves away from the predefined key. 
     After moving the contact to the second location, the user then ends the gesture by providing liftoff of the contact (e.g., a finger-up event). For example, multifunction device  100  detects liftoff of the contact while the contact is outside the predefined key. In response to detecting the liftoff, multifunction device  100  determines that the gesture ended outside of the predefined key. As a result of this determination, multifunction device  100  inserts a character string into text field  508  (e.g., one of the multiple suggested character strings  514 ). In some embodiments, multifunction device  100  further determines that the gesture corresponds to a particular section of suggestion region  506  (e.g., the gesture&#39;s liftoff location is directly above, below, or within a particular section of the suggestion region  506 ). As a result of this determination, multifunction device  100  inserts into text field  508  the suggested character string  514  displayed within that particular section of suggestion region  506 . In some embodiments, the suggested character string  514  displayed within that particular section is inserted regardless of whether that suggested character string is an automatic correction. In some embodiments, inserting the character string replaces the character string that was being entered in text field  508 . In the illustrated embodiment, the gesture&#39;s liftoff location corresponds to suggested character string  514 C, so multifunction device  100  replaces the character string being entered in text field  508  (“Producti”) with character string  514 C (“Productions”), as described above with reference to  FIG. 5C . 
     Referring again to the examples of  FIGS. 5E and 5M  and adding on, the user continues the gesture by moving the contact back within the predefined key. In response to detecting movement of the contact into the predefined key, multifunction device  100  ceases to visually distinguish the suggested character string  514  (that corresponded to the termination point of the previous movement) from the other suggested character strings  514 . In some embodiments, where the visual emphasis of the suggested character string changes based on the distance between the contact and the predefined key, as the contact moves toward the predefined key, the visual emphasis decreases until the contact enters the predefined key and the visual emphasis is nonexistent. 
       FIG. 5F  illustrates an embodiment where the user provides a gesture input on touch screen  112  that begins within a predefined key within the on-screen keyboard region  504 . In the illustrated embodiment in  FIG. 5F , the predefined key is space bar  512 , and multifunction device  100  detects a contact on space bar  512 . However, other predefined keys and/or detected contacts are possible. In  FIG. 5F , the gesture optionally includes movement of a contact from a first location to a second location, where both locations are within the predefined key. (This is different from  FIG. 5D , where the second location was outside the predefined key.) If the gesture includes no movement, then the gesture is essentially a tap on the predefined key. 
     After optionally moving the contact to the second location, the user then ends the gesture by providing liftoff of the contact (e.g., a finger-up event). For example, multifunction device  100  detects liftoff of the contact while the contact is on the predefined key. In the illustrated embodiment in  FIG. 5F , the second location is within the predefined key. In response to detecting the liftoff, multifunction device  100  determines that the gesture ended within the predefined key. As a result of this determination, multifunction device  100  inserts a character string into text field  508 . This is shown in  FIG. 5G . In the illustrated embodiment in  FIG. 5G , the inserted character string is a space character. However, other inserted character strings are possible. In  FIG. 5G , text field  508  displays “Producti”, followed by the inserted space character (not visible). Since cursor  510  is separated from “Producti” by a delimiter character (here, a space), this indicates that the character string is complete. Suggestion region  506  includes multiple suggested character strings  514  for insertion into text field  508  (after “Producti” and the delimiter). 
     In some embodiments, a character string that is inserted when the gesture ends within the predefined key differs from a character string that is inserted when the gesture ends outside of the predefined key. For example, the character string that is inserted when the gesture ends within the predefined key is a space character, while the character string that is inserted when the gesture ends outside of the predefined key is one of the multiple suggested character strings  514 . 
     Recall that, in some embodiments, one of the multiple suggested character strings  514  is the character string that was just entered in text field  508 . In some embodiments, this character string is displayed within quotation marks in suggestion region  506 . This is shown in  FIG. 5H , where the character string that was just entered in text field  508  is “Producti”, and one of the multiple suggested character strings  514  is also “Producti”. In  FIG. 5H , the Producti character string is displayed within quotation marks in suggestion region  506 . The quotation marks notify the user that the enclosed character string is identical to the character string that was just entered in text field  508 . 
     Recall that, in some embodiments, one of the multiple suggested character strings  514  is an automatic correction of a character string being entered in text field  508 . In Figure SI, the character string being entered in text field  508  is “Everybd”. One of the multiple suggested character strings  514  is “Everybody”, which is an automatic correction of “Everybd”. In some embodiments, the automatic correction is displayed in the middle of the multiple suggested character strings  514  and/or is visually distinguished from other suggested character strings that are not automatic corrections. This is shown in  FIG. 5J , where the “Everybody” suggested character string  514  is located in the middle of the multiple suggested character strings  514  and is visually distinguished from the other suggested character strings (“Everybd” and “Everybody&#39;s”). The visual distinction notifies the user that the distinguished character string is an automatic correction of the character string being entered in text field  508 . The automatic correction can be visually distinguished using various techniques, as described above with reference to  FIG. 5B . 
     In some embodiments, the automatic correction is displayed within the predefined key (mentioned above) that can be used to insert a character string into text field  508 . This is shown in the example illustrated in  FIG. 5K , where the predefined key is space bar  512 , and the automatic correction is “Everybody”. In some embodiments, a graphical user interface (GUI) element is displayed adjacent to the automatic correction. This is shown in  FIG. 5L , where the GUI element is an “x” inside a box, and the automatic correction is “Everybody”. When the GUI element is activated, the automatic correction is rejected. In some embodiments, when the automatic correction is rejected, the automatic correction is replaced with a different suggested character string from suggestion region  506 . 
     Note that, in some embodiments, no automatic corrections are presented to the user. For example, when the user has not typed any characters or has typed only a few (e.g., one or two) characters in a current character string, then no automatic correction results are suggested. However, automatic completion results could still be suggested in these situations. 
     Recall that, in  FIG. 5M , the termination point of the movement is directly below (and, therefore, corresponds to) the section in which the “Everybody” suggested character string  514  is displayed. In the illustrated embodiment in  FIG. 5M , the “Everybody” suggested character string  514  is visually distinguished by increasing the height of the section of suggestion region  506  that includes this suggested character string. Adding on to this example, the user continues the gesture by moving the contact point toward a first side of suggestion region  506 . This is shown in  FIG. 5N , where the first side is the right side, and the termination point of the continued movement is directly below (and, therefore, corresponds to) the section on the first side (here, the right side) in which the “Everybody&#39;s” suggested character string  514  is displayed. In response to detecting this gesture, the suggested character string  514  in the first side section is visually distinguished. In the illustrated embodiment in  FIG. 5N , the “Everybody&#39;s” suggested character string  514  is visually distinguished by increasing the height of the section of suggestion region  506  that includes this suggested character string. Together,  FIGS. 5M and 5N  show an upward swipe that starts within the predefined key and moves outside the predefined, followed by a swipe to a first side (here, the right side, but the left side would yield similar results). 
     The user then ends the gesture by providing liftoff of the contact (e.g., a finger-up event). For example, multifunction device  100  detects liftoff of the contact while the contact is directly below the section in which the “Everybody&#39;s” suggested character string  514  is displayed. In response to detecting the liftoff, multifunction device  100  determines that the gesture ended outside the predefined key and further determines that the gesture corresponds to a particular section of suggestion region  506 . As a result of these determinations, multifunction device  100  inserts the “Everybody&#39;s” suggested character string  514  into text field  508 . This is shown in  FIG. 5O . In  FIG. 5O , text field  508  displays “Everybody&#39;s”, followed by a trailing space character (not visible). Suggestion region  506  includes multiple suggested character strings  514  for insertion into text field  508  (after “Everybody&#39;s” and the delimiter). 
       FIGS. 6A-6L  illustrate exemplary user interfaces for updating a set of one or more suggestions in a suggestion region in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the process in  FIG. 8 . 
       FIGS. 6A-6L  illustrate user interface  600 , which can be displayed by, e.g., multifunction device  100 . User interface  600  includes message region  602 , on-screen keyboard region  604 , and suggestion region  606 . Message region  602  includes text field  608  and cursor  610 . On-screen keyboard region  604  includes space bar  612 . Suggestion region  606  includes multiple suggested character strings  614 A,  614 B,  614 C (collectively, “suggested character strings  614 ”). In some embodiments, one or more of the multiple suggested character strings  614  is a prediction of a character string being entered in text field  608 , an automatic correction of a character string being entered in text field  608 , an automatic completion of a character string being entered in text field  608 , or the character string that was just entered in text field  608 . In the illustrated embodiment in  FIG. 6A , suggestion region  606  is displayed above on-screen keyboard region  604 , and the multiple suggested character strings  614  are arranged horizontally within suggestion region  606 . 
     In  FIG. 6A , text field  608  displays “Producti”, which is a character string being entered in text field  608 . Cursor  610  is located immediately after the “Producti” character string, indicating that this string is still being entered. (If cursor  610  were separated from the string by a delimiter character, such as a space or a period, then this would indicate that the character string is complete.) The suggested character strings (“Producti”  614 A, “Production”  614 B, and “Productions”  614 C) are displayed in a left section, a middle section, and a right section of suggestion region  606 , respectively. In the illustrated embodiment in  FIG. 6A , suggested character string  614 A (“Producti”) is the character string that was just entered into text field  608 , suggested character string  614 B (“Production”) is a best prediction of the character string being entered into text field  608 , and suggested character string  614 C (“Productions”) is a second-best prediction of the character string being entered into text field  608 . 
     Multifunction device  100  receives one or more entered characters. After receiving the one or more entered characters, multifunction device  100  displays suggestion region  606 . Suggestion region  606  includes a set of one or more suggestions including one or more character strings. The character strings start with the one or more entered characters. This is shown in  FIG. 6A , where the entered characters are “Producti” and the character strings are “Producti”  614 A, “Production”  614 B, and “Productions”  614 C. 
     While displaying the set of one or more suggestions, multifunction device  100  receives one or more additional entered characters. Responsive to receiving the one or more additional entered characters, multifunction device  100  updates the set of suggestions  614 . In some embodiments, multifunction device  100  ceases updating the set of suggestions  614  if the user is typing quickly (e.g., more than 2.2 characters per second). Before the user reaches the threshold speed, the suggestions change every time a character is entered. After the user reaches the threshold speed, there are no updates (e.g., on the theory that the user is not looking at the suggestions if the user is typing that fast). In some embodiments, “no updates” means that the suggestions are frozen, are hidden, or fade out. The automatic suggestion update can require a significant amount of device power. Ceasing to update the set of suggestions  614  if the user is typing quickly (and, presumably, not looking at the suggestions) is an optimization that saves device power. 
     The updating comprises changing a first suggestion in the set of one or more suggestions from a first character string to a second character string. This changing comprises, while maintaining display of a first portion of the first character string, ceasing to display a second portion of the first character string that is incompatible with the one or more additional entered characters. In some embodiments, the first portion of the first character string is the one or more entered characters. 
     This is shown in  FIG. 6B , where the one or more additional entered characters is “v”, the first character string is “Production” (suggested character string  614 B), the first portion of the first character string is “Producti”, and the second portion of the first character string is “on”. Originally, in  FIG. 6A , the entered characters were “Producti”, so the suggested character strings were “Producti”  614 A, “Production”  614 B, and “Productions”  614 C. Then, one additional entered character was received, “v”. That changed the text string being entered to “Productiv”, which is incompatible with “Production”. Responsive to receiving “v”, multifunction device  100  maintained display of the first portion (“Producti”) of the first character string (“Production”) and ceased to display the second portion of the first character string (“on”). 
     In some embodiments, the ceasing to display the second portion of the first character string is performed by instantly removing the second portion from display. In some embodiments, the ceasing to display the second portion is performed by showing an animation that gradually ceases to display the second portion over time. One example of such an animation is a “type-off” animation, where the second portion is removed character-by-character (e.g., starting with the character at the end of the first character string). Another example of such an animation is a fade out animation, where the second portion fades out over time. Yet another example of such an animation is a shrinking animation, where the second portion decreases in size over time. Additional examples of animations for replacing one character string with another character string are described below with reference to  FIGS. 9A-9O and 10 . 
     Changing the first suggestion in the set of one or more suggestions from the first character string to the second character string further comprises, while maintaining display of the first portion of the first character string, adding the one or more additional entered characters to the first portion of the first character string. This is shown in  FIG. 6C , where the one or more additional entered characters is “v”, and the first portion of the first character string is “Producti”. The multifunction device  100  adds the additional entered character, “v”, to “Producti” to form “Productiv”, as shown in  FIG. 6C . 
     In some embodiments, the adding the one or more additional entered characters to the first portion of the first character string is performed by instantly adding the one or more additional entered characters to the display. In some embodiments, the adding the one or more additional entered characters to the first portion is performed by showing an animation that gradually displays the one or more additional entered characters over time. 
     Changing the first suggestion in the set of one or more suggestions from the first character string to the second character string further comprises, while maintaining display of the first portion of the first character string, adding a first set of one or more predicted characters to the first portion of the first character string to display the second character string. This is shown in  FIG. 6D , where the first set of one or more predicted characters is “e”, the first portion of the first character string is “Productiv”, and the second character string is “Productive”. The multifunction device  100  adds the predicted character, “e”, to “Productiv” to form “Productive”, as shown in  FIG. 6D . 
     In some embodiments, the adding the first set of one or more predicted characters to the first portion of the first character string is performed by instantly adding the first set of one or more predicted characters to the display. In some embodiments, the adding the first set of one or more predicted characters to the first portion is performed by showing an animation that gradually displays the first set of one or more predicted characters over time. One example of such an animation is a “type-on” animation, where the first set of one or more predicted characters is displayed character-by-character (e.g., starting with the character after the end of the first portion of the first character string). Another example of such an animation is a fade in animation, where the first set of one or more predicted characters fades in over time. Yet another example of such an animation is an enlarging animation, where the first set of one or more predicted characters increases in size over time. Additional examples of animations for replacing one character string with another character string are described below with reference to  FIGS. 9A-9O and 10 . 
     In some embodiments, the animation for adding the additional entered characters to the first suggestion differs from the animation for adding the predicted characters to the first suggestion. For example, the additional entered characters are added to the first portion of the first character string as soon as the second portion of the first character string ceases to be displayed. Then, the one or more predicted characters appear over time. 
     In some embodiments, multifunction device  100  also changes a second suggestion in the set of one or more suggestions from a third character string to a fourth character string. This changing comprises, while maintaining display of a first portion of the third character string, ceasing to display a second portion of the third character string that is incompatible with the one or more additional entered characters. 
     This is shown in  FIG. 6B , where the one or more additional entered characters is “v”, the third character string is “Productions” (suggested character string  614 C), the first portion of the third character string is “Producti”, and the second portion of the third character string is “ons”. Responsive to receiving “v”, multifunction device  100  maintained display of the first portion (“Producti”) of the third character string (“Productions”) and ceased to display the second portion of the third character string (“ons”). 
     Changing the second suggestion in the set of one or more suggestions from the third character string to the fourth character string further comprises, while maintaining display of the first portion of the third character string, adding the one or more additional entered characters to the first portion of the third character string. This is shown in  FIG. 6C , where the one or more additional entered characters is “v”, and the first portion of the third character string is “Producti”. The multifunction device  100  adds the additional entered character, “v”, to “Producti” to form “Productiv”, as shown in  FIG. 6C . 
     Changing the second suggestion in the set of one or more suggestions from the third character string to the fourth character string further comprises, while maintaining display of the first portion of the third character string, adding a second set of one or more predicted characters to the first portion of the third character string to display the fourth character string. This is shown in  FIG. 6D , where the second set of one or more predicted characters is “ity”, the first portion of the third character string is “Productiv”, and the fourth character string is “Productivity”. The multifunction device  100  adds the predicted characters, “ity”, to “Productiv” to form “Productivity”, as shown in  FIG. 6D . 
     In some embodiments, the first suggestion and the second suggestion are changed substantially simultaneously or concurrently (e.g., as the first suggestion is changing, the second suggestion is changing as well). 
     Continuing with the scenario in  FIG. 6D ,  FIG. 6E  illustrates an embodiment where the user provides a gesture input including touching and maintaining contact with touch screen  112 . The location of the contact corresponds to the location of a suggested character string  614 . In the illustrated embodiment in  FIG. 6E , the location of the contact corresponds to the location of suggested character string  614 C (“Productivity”). 
     In response to detecting the gesture, multifunction device  100  displays one or more variations of the suggested character string  614 . This is shown in  FIG. 6F , where the one or more variations are “Productivity&#39;s” and “Productivities”. In the illustrated embodiment in  FIG. 6F , the one or more variations are displayed above the contacted character string  614 . 
     Multifunction device  100  receives a user input that comprises moving a contact point and ceasing contact when the contact point is within a particular variation. Responsive to the user input, multifunction device  100  inserts the particular variation into a text field. This is shown in  FIG. 6G , where the particular variation is “Productivity&#39;s”, and in  FIG. 6H , where that variation has been inserted into text field  608 . 
     Multifunction device  100  receives a user input that comprises a gesture. Responsive to the user input, multifunction device  100  replaces display of suggestion region  606  with an edit menu. For example, multifunction device  100  displays an animation of the suggestions scrolling out of suggestion region  606  and the edit menu scrolling into the suggestion region. This is shown in  FIG. 6I , where the gesture includes a swipe that begins within suggestion region  606  and moves left or right (here, right). In some embodiments, the gesture includes selecting text within a text field. In some embodiments, the edit menu includes one or more of the following menu items: undo, cut, copy, paste, navigate left one character, and navigate right one character. This is shown in  FIG. 6J . 
     In response to detecting the gesture, multifunction device  100  displays one or more variations of the suggested character string  614 . This is shown in  FIG. 6F , where the one or more variations are “Productivity&#39;s” and “Productivities”. In the illustrated embodiment in  FIG. 6F , the one or more variations are displayed above the contacted character string  614 . 
     Multifunction device  100  detects a movement of a contact downward, starting at a location that corresponds to suggestion region  606 . This is shown in  FIG. 6K . Responsive to the movement, multifunction device  100  ceases to display suggestion region  606 . This is shown in  FIG. 6L , where suggestion region  606  is absent. In some embodiments, ceasing to display suggestion region  606  includes displaying an animation of suggestion region  606  sliding downward into/under on-screen keyboard region  604 . In some embodiments, in response to detecting an upward swipe near a top of on-screen keyboard region  604  while suggestion region  606  is hidden, suggestion region  606  is redisplayed. In some embodiments, the hidden/revealed state of suggestion region  606  is persistent across different applications on the device, so that if suggestion region  606  is hidden in one application, then when the on-screen keyboard is displayed in a different application, suggestion region  606  is also hidden in that application. Whereas, if suggestion region  606  is revealed in one application when the on-screen keyboard is displayed in another application, then suggestion region  606  is also displayed for that on-screen keyboard. In some embodiments, the hidden/revealed state of the on-screen keyboard is set for different applications. 
       FIGS. 9A-9O , described below after  FIG. 8 , illustrate exemplary user interfaces for displaying a transition from a first character string to a second character string in accordance with some embodiments. 
       FIG. 7  is a flow diagram illustrating a method  700  of inserting a character string into a text field in accordance with some embodiments. The method  700  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  700  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  700  provides a faster way to insert a character string into a text field. The method reduces the time that a user requires to insert a character string into a text field, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to insert a character string into a text field faster and more efficiently conserves power and increases the time between battery charges. 
     In some embodiments, an electronic device (e.g., multifunction device  100  with a display and a touch-sensitive surface displays ( 702 ), on a display, a suggestion region (e.g., suggestion region  506  in  FIGS. 5A-5O ). The suggestion region is displayed above an on-screen keyboard (e.g., on-screen keyboard region  504  in  FIGS. 5A-5O ). The suggestion region includes multiple suggested character strings (e.g., suggested character strings  514  in  FIGS. 5A-5O ). 
     The device detects ( 704 ) a gesture (e.g.,  FIGS. 5D, 5F, and 5M ) that begins within a predefined key of the on-screen keyboard (e.g., space bar  512  within on-screen keyboard region  504  in  FIGS. 5A-5O ). 
     Responsive to detecting the gesture, the device inserts ( 706 ) a first character string or a second character into a text field (e.g., text field  508  in  FIGS. 5A-5O ). Specifically, in accordance with a determination that the gesture ends within the predefined key (e.g.,  FIG. 5F ), the device inserts a first character string (e.g., a space character) into a text field. In accordance with a determination that the gesture ends outside of the predefined key (e.g.,  FIGS. 5D and 5M ), the device inserts a second character string into the text field (e.g., one of the suggested character strings  514  in  FIGS. 5A-5O ), wherein the second character string is different from the first character string. 
     It should be understood that the particular order in which the operations in  FIG. 7  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., methods  800  and  1000 ) are also applicable in an analogous manner to method  700  described above with respect to  FIG. 7 . For example, the contacts, gestures, and user interface objects described above with reference to method  700  optionally have one or more of the characteristics of the contacts, gestures, and user interface objects described herein with reference to other methods described herein (e.g., methods  800  and  1000 ). For brevity, these details are not repeated here. 
       FIG. 8  is a flow diagram illustrating a method  800  of updating a set of one or more suggestions in a suggestion region in accordance with some embodiments. The method  800  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  800  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  800  provides a more intuitive way to update a set of one or more suggestions in a suggestion region. The method reduces the cognitive burden on the user when updating a set of one or more suggestions, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, updating a set of one or more suggestions more efficiently conserves power and increases the time between battery charges. 
     In some embodiments, an electronic device (e.g., multifunction device  100  with a display and a touch-sensitive surface receives ( 802 ) one or more entered characters (e.g., “Producti” in  FIG. 6A ). 
     The device displays ( 804 ), on a display, a suggestion region (e.g., suggestion region  606  in  FIG. 6A ). The suggestion region includes a set of one or more suggestions. For example, after receiving the one or more entered characters, the device displays suggestion region  606 . The set of one or more suggestions includes one or more character strings (e.g., suggested character strings  614  in  FIG. 6A ) that start with the one or more entered characters. 
     The device receives ( 806 ) one or more additional entered characters (e.g., “v” in  FIG. 8B ). For example, while displaying the set of one or more suggestions, the device receives one or more additional entered characters. 
     The device updates ( 808 ) the set of suggestions. For example, responsive to receiving the one or more additional entered characters, the device updates the set of suggestions (e.g., suggested character strings  614 ). The updating comprises changing a first suggestion in the set of one or more suggestions from a first character string to a second character string. The changing comprises, while maintaining display of a first portion (e.g., “Producti” in  FIG. 6B ) of the first character string (e.g., “Production” in  FIG. 6A ): ceasing to display ( FIG. 6B ) a second portion (e.g., “on” in  FIG. 6A ) of the first character string that is incompatible with the one or more additional entered characters; adding ( FIG. 6C ) the one or more additional entered characters (e.g., “v”) to the first portion (e.g., “Producti”) of the first character string (e.g., “Production”); and adding ( FIG. 6D ) a first set of one or more predicted characters (e.g., “e” in  FIG. 6D ) to the first portion (e.g., “Productiv”) of the first character string to display the second character string (e.g., “Productive”). 
     It should be understood that the particular order in which the operations in  FIG. 8  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., methods  700  and  1000 ) are also applicable in an analogous manner to method  800  described above with respect to  FIG. 8 . For example, the contacts, gestures, and user interface objects described above with reference to method  800  optionally have one or more of the characteristics of the contacts, gestures, and user interface objects described herein with reference to other methods described herein (e.g., methods  700  and  1000 ). For brevity, these details are not repeated here. 
       FIGS. 9A-9O  illustrate exemplary user interfaces for displaying a transition from a first character string to a second character string in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the process in  FIG. 10 . 
       FIGS. 9A-9O  illustrate user interface  900 , which can be displayed by, e.g., multifunction device  100 . User interface  900  includes message region  902 , on-screen keyboard region  904 , and suggestion region  906 . Message region  902  includes text field  908  and cursor  910 . On-screen keyboard region  904  includes space bar  912 . Suggestion region  906  includes multiple suggested character strings  914 A,  914 B,  914 C (collectively, “suggested character strings  914 ”). In some embodiments, one or more of the multiple suggested character strings  914  is a suggested replacement for characters entered in text field  908 , a prediction of a character string being entered in text field  908 , an automatic correction of a character string being entered in text field  908 , an automatic completion of a character string being entered in text field  908 , or the character string that was just entered in text field  908 . In the illustrated embodiment in  FIG. 9A , suggestion region  906  is displayed above on-screen keyboard region  904 , and the multiple suggested character strings  914  are arranged horizontally within suggestion region  906 . 
     In  FIG. 9A , text field  908  displays “Producti”, which is a character string being entered in text field  908 . Cursor  910  is located immediately after the “Producti” character string, indicating that this string is still being entered. (If cursor  910  were separated from the string by a delimiter character, such as a space or a period, then this would indicate that the character string is complete.) The suggested character strings (“Producti”  914 A, “Production”  914 B, and “Productions”  914 C) are displayed in a left section, a middle section, and a right section of suggestion region  906 , respectively. In the illustrated embodiment in  FIG. 9A , suggested character string  914 A (“Producti”) is the character string that was just entered into text field  908 , suggested character string  914 B (“Production”) is a first suggested replacement for characters entered in text field  908 , and suggested character string  914 C (“Productions”) is a second suggested replacement for characters entered in text field  908 . 
     Multifunction device  100  receives inputs of a first set of one or more entered characters. In some embodiments, the inputs are received in the on-screen keyboard region  904 . After receiving the first set of entered characters, multifunction device  100  displays suggestion region  906  proximate to the on-screen keyboard region  904 . Suggestion region  906  includes a set of one or more suggestions including one or more character strings that are suggested replacements for the first set of entered characters. This is shown in  FIG. 9A , where the entered characters are “Producti” and the character strings are “Producti”  914 A, “Production”  914 B, and “Productions”  914 C. 
     While displaying the set of suggestions, multifunction device  100  receives one or more additional entered characters. After receiving the additional entered characters, multifunction device  100  updates the set of suggestions  914  based on an updated set of entered characters that includes the first set of entered characters and the additional entered characters. (In some embodiments, while displaying the set of suggestions, multifunction device  100  receives deletions of previously-entered characters. After receiving the deletions, multifunction device  100  updates the set of suggestions  914  based on an updated set of entered characters that includes the first set of entered characters excluding any deleted characters.) In some embodiments, multifunction device  100  ceases updating the set of suggestions  914  if the user is typing quickly (e.g., more than 2.2 characters per second). Before the user reaches the threshold speed, the suggestions change every time a character is entered. After the user reaches the threshold speed, there are no updates (e.g., on the theory that the user is not looking at the suggestions if the user is typing that fast). In some embodiments, “no updates” means that the suggestions are frozen, are hidden, or fade out. The automatic suggestion update can require a significant amount of device power. Ceasing to update the set of suggestions  914  if the user is typing quickly (and, presumably, not looking at the suggestions) is an optimization that saves device power. 
     The updating comprises changing a first suggestion in the set of suggestions from a first character string that is a suggested replacement for the first set of entered characters to a second character string that is a suggested replacement for the updated set of entered characters. In some embodiments, changing the first suggestion from the first character string to the second character string comprises determining a deleted portion of the first character string that is deleted relative to the second character string and while displaying the maintained portion of the first character string, sequentially removing the characters of the deleted portion of the first character string. This is shown in  FIG. 9B , where the first character string is “Production” (suggested character string  914 B), the second character string is “Productive” (not yet shown), the maintained portion of the first character string is “Producti”, and the deleted portion of the first character string is “on”. 
     Originally, in  FIG. 9A , the entered characters were “Producti”, so the suggested character strings were “Producti”  914 A, “Production”  914 B, and “Productions”  914 C. Then, one additional entered character was received, “v”. That changed the text string being entered to “Productiv”, which is incompatible with “Production”. After receiving “v”, multifunction device  100  sequentially removes the characters of the deleted portion (“on”) of the first character string while continuing to display the maintained portion (“Producti”) of the first character string. 
     In some embodiments, the characters of the deleted portion are removed starting with a right-most character and ending with a left-most character of the deleted portion. This is shown in  FIGS. 9B and 9C , where the right-most character “n” of the deleted portion “on” is removed first and “o” is removed second. In some embodiments, sequentially removing the characters comprises decreasing a size of an individual character (e.g., gradually over time until the individual character reaches a predetermined minimum size or disappears). This is shown in  FIG. 9B , where the character being removed (“o”) has a decreased size. 
     Eventually, the characters of the deleted portion of the first character string have all been removed, leaving behind the maintained portion of the first character string. This is shown in  FIG. 9C , where the first character string is “Production” (suggested character string  914 B), the second character string is “Productive” (not yet shown), the maintained portion of the first character string is “Producti”, and the deleted portion of the first character string is “on”. 
     In some embodiments, changing the first suggestion from a first character string to a second character string comprises determining a maintained portion of the first character string that is identical to a corresponding portion of the second character string, determining an inserted portion of the second character string that is inserted relative to the maintained portion of the first character string, and while displaying the maintained portion of the first character string, sequentially displaying the characters of the inserted portion of the second character string after the maintained portion of the first character string. In some embodiments, the maintained portion of the first character string is the first set of entered characters. In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining, based on a predefined criterion, whether to entirely replace the first character string with the second character string. In some embodiments, this criterion is whether the two character strings are related forms of each other or different character strings. 
     This is shown in  FIG. 9D , where the first character string is “Production” (suggested character string  914 B), the second character string is “Productive” (not yet shown), the one or more additional entered characters is “v”, the maintained portion of the first character string is “Producti”, and the inserted portion of the second character string is “ye”. Originally, in  FIG. 9A , the entered characters were “Producti”, so the suggested character strings were “Producti”  914 A, “Production”  914 B, and “Productions”  914 C. Then, one additional entered character was received, “v”. That changed the text string being entered to “Productiv”, which is incompatible with “Production”. After receiving “v”, multifunction device  100  sequentially displays the characters of the inserted portion (“ye”) of the second character string after the maintained portion (“Producti”) of the first character string. 
     In some embodiments, sequentially displaying the characters comprises displaying a first character without displaying a second character. This is shown in  FIG. 9D , where multifunction device  100  displays only “v” after the maintained portion (“Producti”) to form “Productiv”. While displaying the first character, the second character is displayed. This is shown in  FIG. 9E , where multifunction device  100  displays “e” after “Prodicti” and “v” to form “Productive”. In some embodiments, the second character is displayed while the appearance of the first character is changing (e.g., while the first character is changing in size and/or opacity) (not shown). 
     In some embodiments, the characters of the inserted portion of the second character string are displayed starting with a left-most character and ending with a right-most character of the inserted portion of the second character string. This is shown in  FIGS. 9D and 9E , where the left-most character “v” of the inserted portion “ye” is displayed first and “e” is displayed second. In some embodiments, sequentially displaying the characters comprises displaying an individual character using a size smaller than a size of characters within the maintained portion of the first character string and after displaying the individual character, increasing the individual character&#39;s size (e.g., gradually over time). This is shown in  FIG. 9D , where the character being displayed (“v”) has a decreased size. 
     Eventually, the characters of the inserted portion of the second character string have all been displayed after the maintained portion of the first character string, resulting in the second character string. This is shown in  FIG. 9F , where the first character string is “Production” (suggested character string  914 B), the second character string is “Productive”, the maintained portion of the first character string is “Producti”, and the inserted portion of the second character string is “ve”. Changing the first suggestion from the first character string (“Production”) to the second character string (“Productive”) is further illustrated in  FIG. 9L , discussed below after  FIG. 9K . 
     In some embodiments, sequentially displaying the characters comprises displaying an individual character using a size smaller than a size of characters within the maintained portion of the first character string and after displaying the individual character, increasing the individual character&#39;s size (e.g., gradually over time). This is shown in  FIG. 9G , where the maintained portion of the first character string (“Producti”) and the individual character (“v”) are shown at successive points in time. The changes shown in  FIG. 9G  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9G  shows only one suggestion and omits the remainder of user interface  900 .) 
     In some embodiments, an anchor point that corresponds to a bottom of the individual character remains at a fixed location relative to the maintained portion of the first character string as the individual character&#39;s size increases. This is also shown in  FIG. 9G . In some embodiments, the individual character is displayed using the size that is less than two-thirds (e.g., half) of the size of characters within the maintained portion of the first character string. This is also shown in  FIG. 9G . 
     In some embodiments, sequentially displaying the characters comprises displaying an individual character using an opacity less than an opacity of the maintained portion of the first character string and after displaying the individual character, increasing the individual character&#39;s opacity (e.g., gradually over time). This is shown in  FIG. 9H , where the maintained portion of the first character string (“Producti”) and the individual character (“v”) are shown at successive points in time. The changes shown in  FIG. 9H  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9H  shows only one suggestion and omits the remainder of user interface  900 .) 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a deleted portion of the first character string that is deleted relative to the second character string (the deleted portion having a second sequence of characters) and while displaying the maintained portion of the first character string, sequentially removing the characters of the deleted portion of the first character string. This is shown in  FIG. 9I , where the first character string is “Production” (suggested character string  914 B), the second character string is “Productive” (not yet shown), the maintained portion of the first character string is “Producti”, and the deleted portion of the first character string is “on”. Originally, in  FIG. 9A , the entered characters were “Producti”, so the suggested character strings were “Producti”  914 A, “Production”  914 B, and “Productions”  914 C. Then, one additional entered character was received, “v”. That changed the text string being entered to “Productiv”, which is incompatible with “Production”. After receiving “v”, multifunction device  100  continues displaying the maintained portion (“Producti”) of the first character string (“Production”). The changes shown in  FIG. 9I  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). 
     While displaying the maintained portion (“Producti”) of the first character string (“Production”), multifunction device  100  sequentially removes the characters of the deleted portion of the first character string (“on”). This is shown in  FIG. 9I , where the maintained portion of the first character string (“Producti”) and the deleted portion (“on”) are shown at successive points in time. (For clarity,  FIG. 9I  shows only one suggestion and omits the remainder of user interface  900 .) In some embodiments, the characters of the deleted portion are removed starting with a right-most character and ending with a left-most character of the deleted portion. This is shown in  FIG. 9I . 
     In some embodiments, sequentially removing the characters comprises decreasing a size of an individual character (e.g., gradually over time until the individual character reaches a predetermined minimum size or disappears). This is shown in  FIG. 9J , where the maintained portion of the first character string (“Producti”) and the individual character (“o”) are shown at successive points in time. The changes shown in  FIG. 9J  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9J  shows only one suggestion and omits the remainder of user interface  900 .) In some embodiments, the removal (or addition) of each character occurs over a predefined time period. In some embodiments, the transition from a first character string to a second character string occurs over a predefined time period (e.g., so that changes that include the addition or removal of a large number of characters take the same or substantially the same amount of time as changes that include the addition or removal of a smaller number of characters). 
     In some embodiments, sequentially removing the characters comprises decreasing an opacity of an individual character until the individual character disappears (e.g., gradually over time). This is shown in  FIG. 9K , where the maintained portion of the first character string (“Producti”) and the individual character (“o”) are shown at successive points in time. The changes shown in  FIG. 9K  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9K  shows only one suggestion and omits the remainder of user interface  900 .) 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises moving the maintained portion of the first character string to a location where the corresponding portion appears within the second character string when the second character string is displayed. For example, in some embodiments, the first character string and the second character string are aligned (e.g., centered) within a predefined region, and the maintained portion moves to account for the alignment of the maintained portion relative to the predefined region when displayed in the first character string as compared with the alignment of the maintained portion relative to the predefined region when displayed in the second character string. 
     In some embodiments, while sequentially displaying the characters of the inserted portion of the second character string, multifunction device  100  moves the displayed maintained portion of the first character string. For example, multifunction device  100  moves the displayed maintained portion of the first character string to a final location determined based on the final location of the second character string when it is aligned (e.g., centered) within a predefined region on the display (e.g., within one of the sections of suggestion region  906  in  FIG. 9A ). 
     Returning to the example shown in  FIGS. 9A-9F , changing the first suggestion from the first character string to the second character string is further illustrated in  FIG. 9L . In  FIG. 9L , the first character string is “Production” (suggested character string  914 B), the second character string is “Productive”, the maintained portion of the first character string is “Producti”, the deleted portion of the first character string is “on”, and the inserted portion of the second character string is “ye”. Characters of the deleted portion are removed by decreasing their size. Characters of the inserted portion are displayed by increasing their size. In  FIG. 9L , the maintained portion, the deleted portion, and the inserted portion are shown at successive points in time. The changes shown in  FIG. 9L  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9L  shows only one suggestion and omits the remainder of user interface  900 .) 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a replaced portion of the first character string that is replaced by a replacement portion of the second character string (the replaced portion having a second sequence of characters and the replacement portion having a third sequence of characters) and while displaying the maintained portion of the first character string, sequentially replacing characters of the replaced portion with characters of the replacement portion. 
     In some embodiments, as a replaced character is deleted, the replaced character is replaced by a replacement character (e.g., to avoid the appearance of gaps). For example, the display of a replacement character is timed to coincide with (e.g., to occur concurrently with or just after) ceasing to display the character that it is replacing. 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a second maintained portion of the first character string and a second corresponding portion of the second character string that match, determining a replaced portion of the first character string that is between the maintained portion of the first character string and the second maintained portion of the first character string (the replaced portion having a second sequence of characters), determining a replacement portion of the second character string that is between the corresponding portion of the second character string and the second corresponding portion of the second character string (the replacement portion having a third sequence of characters), and while displaying the maintained portion of the first character string and the second maintained portion of the first character string, sequentially replacing characters of the replaced portion with characters of the replacement portion. 
     This is shown in  FIG. 9M , where the first character string is “bookseller”, the second character string is “bookkeeper”, the maintained portion of the first character string and the corresponding portion of the second character string are “book”, the second maintained portion of the first character string and the second corresponding portion of the second character string are “er”, the replaced portion of the first character string is “sell”, and the replacement portion of the second character string is “keep”. In  FIG. 9M , the maintained portion, the second maintained portion, the replaced portion, and the replacement portion are shown at successive points in time. The changes shown in  FIG. 9M  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9M  shows only one suggestion and omits the remainder of user interface  900 .) 
     Specifically,  FIG. 9M  shows the following character strings in order: 
     “bookseller” (first character string); 
     “bookseller” where the “s” is overlaid by a “k” (“s” being replaced by “k”); 
     “bookkeller” (“s” was replaced by “k”); 
     “bookkeller” where the first “l” is overlaid by an “e” (“l” being replaced by “e”); 
     “bookkeeler” (“l” was replaced by “e”); 
     “bookkeeler” where the “l” is overlaid by a “p” (“l” being replaced by “p”); 
     “bookkeeper” (second character string; “l” was replaced by “p”). 
     In some embodiments, multifunction device  100  determines an order in which characters are sequentially replaced based on a location of the replaced portion within the first character string. For example, in accordance with a determination that the replaced portion is located in the middle of the first character string, sequentially replacing the characters of the replaced portion with the characters of the replacement portion in a first direction. In accordance with a determination that the replaced portion is located at the end of the first character string, sequentially replacing the characters of the replaced portion with the characters of the replacement portion in a second direction that is different from or opposite to the first direction. 
     In some embodiments, multifunction device  100  determines an order in which characters are sequentially replaced based on whether the replaced portion is longer than the replacement portion. For example, in accordance with a determination that the replaced portion is longer than the replacement portion, sequentially replacing the characters of the replaced portion with the characters of the replacement portion in a first direction. In accordance with a determination that the replaced portion is shorter than the replacement portion, sequentially replacing the characters of the replaced portion with the characters of the replacement portion in a second direction that is different from or opposite to the first direction. 
     In some embodiments, the replacement portion is longer than the replaced portion, and sequentially replacing characters of the replaced portion with characters of the replacement portion comprises determining a first portion of the replacement portion that is equal in length to the replaced portion, determining a remainder portion of the replacement portion that follows the first portion of the replacement portion, replacing the replaced portion with the first portion of the replacement portion without moving the first maintained portion of the first character string relative to the second maintained portion of the first character string (in some embodiments, the characters in the first portion of the replacement portion are substituted character by character), moving the first maintained portion of the first character string relative to the second maintained portion of the first character string (e.g., moving the first portion of the replacement portion away from the second corresponding portion of the second character string) by one character width, and displaying a first character of the remainder portion after the first portion of the replacement portion and before the second corresponding portion of the second character string. 
     This is shown in  FIG. 9N , where the first character string is “disgusted”, the second character string is “disinterested”, the maintained portion of the first character string and the corresponding portion of the second character string are “dis”, the second maintained portion of the first character string and the second corresponding portion of the second character string are “sted”, the replaced portion of the first character string is “gu”, the replacement portion of the second character string is “intere”, the first portion of the replacement portion is “in”, the remainder portion of the replacement portion is “tere”, and the first character of the remainder portion is “t”. Characters of the remainder portion are displayed by increasing their size. In  FIG. 9N , the maintained portion, the second maintained portion, the replaced portion, and the replacement portion are shown at successive points in time. The changes shown in  FIG. 9N  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9N  shows only one suggestion and omits the remainder of user interface  900 .) 
     Specifically,  FIG. 9N  shows the following character strings in order: 
     “disgusted” (first character string); 
     “disiusted” (“g” was replaced by “i”); 
     “disinsted” (“u” was replaced by “n”); 
     “disintsted” where the first “t” is smaller (“t” being added); 
     “disintsted” (“t” at full size); 
     “disintested” where the first “e” is smaller (“e” being added); 
     “disintested” (“e” at full size); 
     “disintersted” where the “r” is smaller (“r” being added); 
     “disintersted” (“r” at full size); 
     “disinterested” where the second “e” is smaller (“e” being added); 
     “disinterested” (second character string; “e” at full size). 
     In some embodiments, the first character of the remainder portion is a left-most character of the remainder portion. This is shown in  FIG. 9N . After displaying the first character of the remainder portion, other characters to the right of the first character are subsequently displayed. 
     In some embodiments, the replacement portion is shorter than the replaced portion, and sequentially replacing characters of the replaced portion with characters of the replacement portion comprises determining a first portion of the replaced portion that is equal in length to the replacement portion, determining a remainder portion of the replaced portion that follows the first portion of the replaced portion, removing from the first character string a first character of the remainder portion, and moving the second corresponding portion of the second character string towards the first portion of the replaced portion by one character width (e.g., without waiting for other characters in the first portion of the replaced portion to be replaced with characters of the replacement portion). 
     This is shown in  FIG. 9O , where the first character string is “disinterested”, the second character string is “disgusted”, the maintained portion of the first character string and the corresponding portion of the second character string are “dis”, the second maintained portion of the first character string and the second corresponding portion of the second character string are “sted”, the replaced portion of the first character string is “intere”, the first portion of the replaced portion is “in”, the remainder portion of the replaced portion is “tere”, the first character of the remainder portion is “e”, and the replacement portion of the second character string is “gu”. Characters of the remainder portion are removed by decreasing their size. In  FIG. 9O , the maintained portion, the second maintained portion, the replaced portion, and the replacement portion are shown at successive points in time. The changes shown in  FIG. 9O  correspond to different stages in an animation and, thus, in some embodiments, occur automatically after receiving a change to the entered characters (e.g., in response to detecting entry of the additional entered character “v”). (For clarity,  FIG. 9O  shows only one suggestion and omits the remainder of user interface  900 .) 
     Specifically,  FIG. 9O  shows the following character strings in order: 
     “disinterested” (first character string); 
     “disinterested” where the second “e” is smaller (“e” being removed); 
     “disintersted” (“e” was removed); 
     “disintersted” where the “r” is smaller (“r” being removed); 
     “disintested” (“r” was removed); 
     “disintested” where the first “e” is smaller (“e” being removed); 
     “disintsted” (“e” was removed); 
     “disintsted” where the first “t” is smaller (“t” being removed); 
     “disinsted” (“t” was removed); 
     “disiusted” (“n” was replaced by “u”) 
     “disgusted” (second character string; “i” was replaced by “g”). 
     In some embodiments, the first character of the remainder portion is a right-most character of the remainder portion. This is shown in  FIG. 9O . After removing the first character of the remainder portion, other characters to the left of the first character are subsequently removed. 
     In some embodiments, updating the set of suggestions  914  based on the updated set of entered characters (that includes the first set of entered characters and the additional entered characters) further comprises changing a second suggestion in the set of suggestions from a third character string that is a suggested replacement for the first set of entered characters to a fourth character string that is a suggested replacement for the updated set of entered characters. 
     Note that the first suggestion in the set of suggestions need not be changed in the same way as the second suggestion in the set of suggestions. For example, the first suggestion might be changed such that a) an inserted portion of the second character string is inserted relative to a maintained portion of the first character string, b) a deleted portion of the first character string is deleted relative to the second character string, c) a maintained portion of the first character string is moved to a location where a corresponding portion appears within the second character string when the second character string is displayed, or d) a replaced portion of the first character string is replaced by a replacement portion of the second character string. The second suggestion might be changed in any of these ways and need not be changed in the same way as the first suggestion. Similarly, even if the first suggestion is changed in the same way as the second suggestion (e.g., both have inserted portions and maintained portions), the character string portions need not be identical. For example, the maintained portion of the first suggestion might differ from the maintained portion of the second suggestion. 
     Changing the second suggestion from a third character string to a fourth character string comprises determining a maintained portion of the third character string that is identical to a corresponding portion of the fourth character string, determining an inserted portion of the fourth character string that is inserted relative to the maintained portion of the third character string (the inserted portion having a second sequence of characters), and while displaying the maintained portion of the third character string, sequentially displaying the characters of the inserted portion of the fourth character string after the maintained portion of the third character string. In some embodiments, the first suggestion and the second suggestion are changed concurrently (e.g., substantially simultaneously). 
     This is shown in  FIG. 9C , where the third character string is “Productions” (suggested character string  914 C), the fourth character string is “Productivity” (not yet shown), the one or more additional entered characters is “v”, the maintained portion of the third character string is “Producti”, and the inserted portion of the fourth character string is “vity”. Originally, in  FIG. 9A , the entered characters were “Producti”, so the suggested character strings were “Producti”  914 A, “Production”  914 B, and “Productions”  914 C. Then, one additional entered character was received, “v”. That changed the text string being entered to “Productiv”, which is incompatible with “Productions”. After receiving “v”, multifunction device  100  continues displaying the maintained portion (“Producti”) of the third character string (“Productions”). 
     While displaying the maintained portion (“Produci”) of the third character string (“Productions”), multifunction device  100  sequentially displays the characters of the inserted portion of the fourth character string (“vity”) after the maintained portion of the third character string. In some embodiments, sequentially displaying the characters comprises displaying a first character without displaying a second character. This is shown in  FIG. 9D , where multifunction device  100  displays only “vit” after the maintained portion (“Producti”) to form “Productivit”. While displaying the first character, the second character is displayed (and possibly additional characters are displayed). This is shown in  FIG. 9E , where multifunction device  100  displays “y” after “Producti” and “vit” to form “Productivity”. 
       FIG. 10  is a flow diagram illustrating a method  1000  of displaying a transition from a first character string to a second character string in accordance with some embodiments. The method  1000  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  1000  are, optionally, combined and/or the order of some operations is, optionally, changed. 
     As described below, the method  1000  provides a more intuitive way to update a set of one or more suggestions. The method reduces the cognitive burden on the user when updating a set of one or more suggestions, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, updating a set of one or more suggestions more efficiently conserves power and increases the time between battery charges. 
     In some embodiments, an electronic device (e.g., multifunction device  100  with a display and a touch-sensitive surface) displays ( 1002 ) a set of one or more suggestions including one or more character strings (e.g., “Producti”  914 A, “Production”  914 B, and “Productions”  914 C in  FIG. 9A ) that are suggested replacements for a first set of one or more entered characters (e.g., “Producti” in  FIG. 9A ). 
     While displaying the set of suggestions, the device receives ( 1004 ) one or more entered characters (e.g., “v” in  FIG. 9B ). 
     After receiving the additional entered characters, the device updates ( 1006 ) the set of suggestions based on an updated set of entered characters (e.g., “Productiv” in  FIG. 9B ) that includes the first set of entered characters and the additional entered characters. The updating comprises changing a first suggestion in the set of suggestions from a first character string (e.g., “Production”  914 B in  FIG. 9A ) that is a suggested replacement for the first set of entered characters to a second character string (e.g., “Productive” in  FIG. 9F ) that is a suggested replacement for the updated set of entered characters. 
     The changing comprises determining a maintained portion (e.g., “Producti”) of the first character string that is identical to a corresponding portion (e.g., “Producti”) of the second character string, determining an inserted portion (e.g., “ye”) of the second character string that is inserted relative to the maintained portion of the first character string (the inserted portion having a sequence of characters), and while displaying the maintained portion of the first character string, sequentially displaying the characters of the inserted portion of the second character string after the maintained portion of the first character string (e.g.,  FIGS. 9D-9F ). 
     It should be understood that the particular order in which the operations in  FIG. 10  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., methods  700  and  800 ) are also applicable in an analogous manner to method  1000  described above with respect to  FIG. 10 . For example, the contacts, gestures, and user interface objects described above with reference to method  1000  optionally have one or more of the characteristics of the contacts, gestures, and user interface objects described herein with reference to other methods described herein (e.g., methods  700  and  800 ). For brevity, these details are not repeated here.

The processing unit  1306  is also configured to, while displaying the set of suggestions, receive one or more additional entered characters (e.g., with the receiving unit  1310 ). The processing unit  1306  is also configured to, after receiving the additional entered characters, update the set of suggestions based on an updated set of entered characters that includes the first set of entered characters and the additional entered characters (e.g., with the updating unit  1312 ). The updating comprises changing a first suggestion in the set of suggestions from a first character string that is a suggested replacement for the first set of entered characters to a second character string that is a suggested replacement for the updated set of entered characters (e.g., using the changing unit  1314 ). The changing comprises determining a maintained portion of the first character string that is identical to a corresponding portion of the second character string (e.g., with the determining unit  1316 ), determining an inserted portion of the second character string that is inserted relative to the maintained portion of the first character string, the inserted portion having a sequence of characters (e.g., with the determining unit  1316 ), and while displaying the maintained portion of the first character string, sequentially displaying the characters of the inserted portion of the second character string after the maintained portion of the first character string (e.g., with the display enabling unit  1308 ). 
     In some embodiments, the processing unit  1306  is further configured to display a keyboard (e.g., with the display enabling unit  1308 ), receive, in the keyboard, inputs of the first set of one or more entered characters (e.g., with the receiving unit  1310 ), and display, proximate to the keyboard, a suggestion region that includes the set of one or more suggestions (e.g., with the display enabling unit  1308 ). 
     In some embodiments, sequentially displaying the characters comprises displaying a first character without displaying a second character (e.g., with the display enabling unit  1308 ) and while displaying the first character, displaying the second character (e.g., with the display enabling unit  1308 ). 
     In some embodiments, sequentially displaying the characters comprises displaying an individual character using a size smaller than a size of characters within the maintained portion of the first character string (e.g., with the display enabling unit  1308 ) and after displaying the individual character, increasing the individual character&#39;s size (e.g., with the increasing unit  1318 ). 
     In some embodiments, an anchor point that corresponds to a bottom of the individual character remains at a fixed location relative to the maintained portion of the first character string as the individual character&#39;s size increases. 
     In some embodiments, the individual character is displayed using the size that is less than two-thirds of the size of characters within the maintained portion of the first character string. 
     In some embodiments, sequentially displaying the characters comprises displaying an individual character using an opacity less than an opacity of the maintained portion of the first character string (e.g., with the display enabling unit  1308 ) and after displaying the individual character, increasing the individual character&#39;s opacity (e.g., with the increasing unit  1318 ). 
     In some embodiments, the characters of the inserted portion of the second character string are displayed starting with a left-most character and ending with a right-most character of the inserted portion of the second character string. 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a deleted portion of the first character string that is deleted relative to the second character string, the deleted portion having a second sequence of characters (e.g., with the determining unit  1316 ) and while displaying the maintained portion of the first character string, sequentially removing the characters of the deleted portion of the first character string (e.g., with the removing unit  1320 ). 
     In some embodiments, sequentially removing the characters comprises decreasing a size of an individual character (e.g., with the decreasing unit  1322 ). 
     In some embodiments, sequentially removing the characters comprises decreasing an opacity of an individual character until the individual character disappears (e.g., with the decreasing unit  1322 ). 
     In some embodiments, the characters of the deleted portion are removed starting with a right-most character and ending with a left-most character of the deleted portion. 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises moving the maintained portion of the first character string to a location where the corresponding portion appears within the second character string when the second character string is displayed (e.g., with the moving unit  1324 ). 
     In some embodiments, the processing unit  1306  is further configured to, while sequentially displaying the characters of the inserted portion of the second character string, move the displayed maintained portion of the first character string (e.g., with the moving unit  1324 ). 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a replaced portion of the first character string that is replaced by a replacement portion of the second character string, the replaced portion having a second sequence of characters and the replacement portion having a third sequence of characters (e.g., with the determining unit  1316 ) and while displaying the maintained portion of the first character string, sequentially replacing characters of the replaced portion with characters of the replacement portion (e.g., with the replacing unit  1326 ). 
     In some embodiments, as a replaced character is deleted, the replaced character is replaced by a replacement character. 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining a second maintained portion of the first character string and a second corresponding portion of the second character string that match (e.g., with the determining unit  1316 ), determining a replaced portion of the first character string that is between the maintained portion of the first character string and the second maintained portion of the first character string, the replaced portion having a second sequence of characters (e.g., with the determining unit  1316 ), determining a replacement portion of the second character string that is between the corresponding portion of the second character string and the second corresponding portion of the second character string, the replacement portion having a third sequence of characters (e.g., with the determining unit  1316 ), and while displaying the maintained portion of the first character string and the second maintained portion of the first character string, sequentially replacing characters of the replaced portion with characters of the replacement portion (e.g., with the replacing unit  1326 ). 
     In some embodiments, the replacement portion is longer than the replaced portion, and sequentially replacing characters of the replaced portion with characters of the replacement portion comprises determining a first portion of the replacement portion that is equal in length to the replaced portion (e.g., with the determining unit  1316 ), determining a remainder portion of the replacement portion that follows the first portion of the replacement portion (e.g., with the determining unit  1316 ), replacing the replaced portion with the first portion of the replacement portion without moving the first maintained portion of the first character string relative to the second maintained portion of the first character string (e.g., with the replacing unit  1326 ), moving the first maintained portion of the first character string relative to the second maintained portion of the first character string by one character width (e.g., with the moving unit  1324 ), and displaying a first character of the remainder portion after the first portion of the replacement portion and before the second corresponding portion of the second character string (e.g., with the display enabling unit  1308 ). 
     In some embodiments, the first character of the remainder portion is a left-most character of the remainder portion. 
     In some embodiments, the replacement portion is shorter than the replaced portion, and sequentially replacing characters of the replaced portion with characters of the replacement portion comprises determining a first portion of the replaced portion that is equal in length to the replacement portion (e.g., with the determining unit  1316 ), determining a remainder portion of the replaced portion that follows the first portion of the replaced portion (e.g., with the determining unit  1316 ), removing, from the first character string, a first character of the remainder portion (e.g., with the removing unit  1320 ), and moving the second corresponding portion of the second character string towards the first portion of the replaced portion by one character width (e.g., with the moving unit  1324 ). 
     In some embodiments, the first character of the remainder portion is a right-most character of the remainder portion. 
     In some embodiments, the processing unit  1306  is further configured to determine an order in which characters are sequentially replaced based on a location of the replaced portion within the first character string (e.g., with the determining unit  1316 ). 
     In some embodiments, the processing unit  1306  is further configured to determine an order in which characters are sequentially replaced based on whether the replaced portion is longer than the replacement portion (e.g., with the determining unit  1316 ). 
     In some embodiments, updating further comprises changing a second suggestion in the set of suggestions from a third character string that is a suggested replacement for the first set of entered characters to a fourth character string that is a suggested replacement for the updated set of entered characters (e.g., with the changing unit  1314 ). Changing comprises determining a maintained portion of the third character string that is identical to a corresponding portion of the fourth character string (e.g., with the determining unit  1316 ), determining an inserted portion of the fourth character string that is inserted relative to the maintained portion of the third character string, the inserted portion having a second sequence of characters (e.g., with the determining unit  1316 ), and while displaying the maintained portion of the third character string, sequentially displaying the characters of the inserted portion of the fourth character string after the maintained portion of the third character string (e.g., with the display enabling unit  1308 ). 
     In some embodiments, the first suggestion and the second suggestion are changed concurrently. 
     In some embodiments, the maintained portion of the first character string is the first set of entered characters. 
     In some embodiments, changing the first suggestion from the first character string to the second character string further comprises determining, based on a predefined criterion, whether to entirely replace the first character string with the second character string (e.g., with the determining unit  1316 ). 
     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. 7, 8, and 10  are, optionally, implemented by components depicted in  FIGS. 1A-1B ,  FIG. 11 ,  FIG. 12 , or  FIG. 13 . For example, displaying operations  702 ,  804 , and  1002 , detection operation  704 , insertion operation  706 , receiving operations  802 ,  806 , and  1004 , and updating operations  808  and  1006  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 (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. 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 uses 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 ,  FIG. 11 ,  FIG. 12 , or  FIG. 13 . 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best use the invention and various described embodiments with various modifications as are suited to the particular use contemplated. 
     Any of the steps, operations, or processes described herein may be performed or implemented with one or more hardware or software modules, alone or in combination with other devices. In one embodiment, a software module is implemented with a computer program product comprising a computer-readable medium containing computer program code, which can be executed by a computer processor for performing any or all of the steps, operations, or processes described. 
     Embodiments of the invention may also relate to an apparatus for performing the operations herein. This apparatus may be specially constructed for the required purposes, and/or it may comprise a general-purpose computing device selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a tangible computer readable storage medium or any type of media suitable for storing electronic instructions, and coupled to a computer system bus. Furthermore, any computing systems referred to in the specification may include a single processor or may be architectures employing multiple processor designs for increased computing capability. 
     Embodiments of the invention may also relate to a computer data signal embodied in a carrier wave, where the computer data signal includes any embodiment of a computer program product or other data combination described herein. The computer data signal is a product that is presented in a tangible medium or carrier wave and modulated or otherwise encoded in the carrier wave, which is tangible, and transmitted according to any suitable transmission method. 
     Finally, the language used in the specification has been principally selected for readability and instructional purposes, and it may not have been selected to delineate or circumscribe the inventive subject matter. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by any claims that issue on an application based hereon. Accordingly, the disclosure of the embodiments of the invention is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
