     TECHNICAL FIELD 
     This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that display electronic documents. 
     BACKGROUND 
     The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate electronic documents on a display. 
     Exemplary manipulations include navigating and editing an electronic document. A user may need to perform such manipulations in any application that includes electronic document viewing and editing capabilities (e.g., a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processing application (e.g., Pages from Apple Inc. of Cupertino, Calif.), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, Calif.)). 
     But existing methods for navigating and editing documents are cumbersome and inefficient, especially on devices with a small form factor, such as handheld or pocket-sized devices. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices. 
     SUMMARY 
     Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for navigating and editing an electronic document. Such methods and interfaces may complement or replace conventional methods for navigating and editing an electronic document. 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 some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions may include image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions may be included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

     DESCRIPTION OF EMBODIMENTS 
     Described below are devices and methods that allow a user to efficiently navigate and edit electronic documents. The methods are particularly useful on portable devices with small displays, including handheld or pocket-sized devices (e.g., smart phones). For such portable devices, a user may find himself (or herself) constantly needing to manually readjust the text display size as the user moves through the document, from a very small text display size to get an overview of the document to a larger text display size to clearly see the text being edited. These adjustments require multiple inputs and extensive hand-eye coordination. Such adjustments quickly become annoying and tiresome to users. The methods described herein include:
         Automatically zooming in on a user-specified insertion point when entering a document editing mode and displaying the text at the insertion point at a target text display size for easy viewing and editing;   Easily modifying the target text display size from a default value to a user-adjusted value;   Automatically adjusting the display magnification to maintain a target text display size as the insertion point is moved between areas in a document with different font sizes;   Automatically zooming out at the completion of a text selection gesture to see the entire portion of text that has been selected;   Automatically zooming to display an object at a size that accommodates the object or, when the object contains editable text, automatically zooming to display the editable text within the object at a size that accommodates the text; and   Automatically switching back and forth from a user-specified magnification level in a document-display mode to a predefined document-editing magnification level in an editing mode.       

     These methods greatly reduce the number of steps that a user has to perform to navigate and edit a document, thereby increasing efficiency and ease of use when performing these tasks. 
     Below,  FIGS. 1A-1B ,  2 ,  3 , and  12 - 17  provide a description of exemplary devices.  FIGS. 4A-4B  and  5 A- 5 AA illustrate exemplary user interfaces for navigating and editing an electronic document.  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  9 A- 9 B,  10 ,  11 A- 11   b  are flow diagrams illustrating methods of navigating and editing an electronic document. The user interfaces in FIGS.  5 A- 5 AA are used to illustrate the processes in  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  9 A- 9 B,  10 ,  11 A- 11 B.

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  may include display controller  156  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  may 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  may be 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 ) may include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons may 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 may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond 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  may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen  112  and display controller  156  may 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  may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make 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  may include 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 may be 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  may include 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  may also include 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  may include 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  may capture 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 may be used 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 may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. 
     Device  100  may also include one or more proximity sensors  166 .  FIG. 1A  shows proximity sensor  166  coupled to peripherals interface  118 . Alternately, proximity sensor  166  may be coupled to input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  may also include one or more accelerometers  168 .  FIG. 1A  shows accelerometer  168  coupled to peripherals interface  118 . Alternately, accelerometer  168  may be 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 . 
     In some embodiments, the software components stored in memory  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or sets of instructions)  136 . Furthermore, in some embodiments memory  102  stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices. 
     Contact/motion module  130  may detect 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 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, may include 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 may be 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. 
     Contact/motion module  130  may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be 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 intensity 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 may be 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 . 
     Text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing, to camera  143  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets). 
     Applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         contacts module  137  (sometimes called an address book or contact list);   telephone module  138 ;   video conferencing module  139 ;   e-mail client module  140 ;   instant messaging (IM) module  141 ;   workout support module  142 ;   camera module  143  for still and/or video images;   image management module  144 ;   browser module  147 ;   calendar module  148 ;   widget modules  149 , which may include one or more of: weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   widget creator module  150  for making user-created widgets  149 - 6 ;   search module  151 ;   video and music player module  152 , which may be made up of a video player module and a music player module;   notes module  153 ;   map module  154 ; and/or   online video module  155 .       

     Examples of other applications  136  that may be stored in memory  102  include other word processing applications (e.g., word processing module  384 ), other image editing applications, drawing applications (e.g., drawing module  380 ), presentation applications (presentation module  382 ), spreadsheet applications (e.g., spreadsheet module  390 ), website creation applications (e.g., website creation module  386 ), JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

     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 may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store 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  may be reduced. 
     The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad 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 may be displayed on device  100 . In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be 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  FIGS. 1A and 1B ) or  370  ( FIG. 3 ) includes event sorter  170  (e.g., in operating system  126 ) and a respective application  136 - 1  (e.g., any of the aforementioned applications  137 - 151 ,  155 ,  380 - 390 ). 
     Event sorter  170  receives event information and determines the application  136 - 1  and application view  191  of application  136 - 1  to which to deliver the event information. Event sorter  170  includes event monitor  171  and event dispatcher module  174 . In some embodiments, application  136 - 1  includes application internal state  192 , which indicates the current application view(s) displayed on touch sensitive display  112  when the application is active or executing. In some embodiments, device/global internal state  157  is used by event sorter  170  to determine which application(s) is (are) currently active, and application internal state  192  is used by event sorter  170  to determine application views  191  to which to deliver event information. 
     In some embodiments, application internal state  192  includes additional information, such as one or more of: resume information to be used when application  136 - 1  resumes execution, user interface state information that indicates information being displayed or that is ready for display by application  136 - 1 , a state queue for enabling the user to go back to a prior state or view of application  136 - 1 , and a redo/undo queue of previous actions taken by the user. 
     Event monitor  171  receives event information from peripherals interface  118 . Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display  112 , as part of a multi-touch gesture). Peripherals interface  118  transmits information it receives from I/O subsystem  106  or a sensor, such as proximity sensor  166 , accelerometer(s)  168 , and/or microphone  113  (through audio circuitry  110 ). Information that peripherals interface  118  receives from I/O subsystem  106  includes information from touch-sensitive display  112  or a touch-sensitive surface. 
     In some embodiments, event monitor  171  sends requests to the peripherals interface  118  at predetermined intervals. In response, peripherals interface  118  transmits event information. In other embodiments, peripheral interface  118  transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration). 
     In some embodiments, event sorter  170  also includes a hit view determination module  172  and/or an active event recognizer determination module  173 . 
     Hit view determination module  172  provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display  112  displays more than one view. Views are made up of controls and other elements that a user can see on the display. 
     Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may 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 may be called the hit view, and the set of events that are recognized as proper inputs may be 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  may utilize or call 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 may 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 may also include 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 may 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, e.g., coordinating mouse movement and mouse button presses with or without single or multiple keyboard presses or holds, user movements 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, which may be 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 may display one or more graphics within user interface (UI)  200 . In this embodiment, as well as others described below, a user may 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 may include 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 embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap. 
     Device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen  112 . 
     In one embodiment, device  100  includes touch screen  112 , menu button  204 , push button  206  for powering the device on/off and locking the device, volume adjustment button(s)  208 , Subscriber Identity Module (SIM) card slot  210 , head set jack  212 , and docking/charging external port  124 . Push button  206  may be 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 may accept verbal input for activation or deactivation of some functions through microphone  113 . 
       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  may 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 may include a keyboard and/or mouse (or other pointing device)  350  and touchpad  355 . Memory  370  includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include 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  may optionally include 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. 1 ), or a subset thereof. Furthermore, memory  370  may store additional programs, modules, and data structures not present in memory  102  of portable multifunction device  100 . For example, memory  370  of device  300  may store 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. 1 ) may or may not store these modules. 
     Each of the above identified elements in  FIG. 3  may be 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 may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory  370  may store a subset of the modules and data structures identified above. Furthermore, memory  370  may store additional modules and data structures not described above. 
     Attention is now directed towards embodiments of user interfaces (“UI”) that may be 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 may be 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:
           Phone  138 , which may include an indicator  414  of the number of missed calls or voicemail messages;   E-mail client  140 , which may include an indicator  410  of the number of unread e-mails;   Browser  147 ; and   Video and music player  152 , also referred to as iPod (trademark of Apple Inc.) module  152 ; and   
           Icons for other applications, such as:
           IM  141 ;   Image management  144 ;   Camera  143 ;   Weather  149 - 1 ;   Stocks  149 - 2 ;   Workout support  142 ;   Calendar  148 ;   Alarm clock  149 - 4 ;   Map  154 ;   Notes  153 ;   Settings  412 , which provides access to settings for device  100  and its various applications  136 ;   Online video module  155 , also referred to as YouTube (trademark of Google Inc.) module  155 ;   Word processor  384 ;   Drawing  380 ;   Spreadsheet  390 ; and   Presentation  382 .   
               

       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 ). Although many 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 may be 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 may be 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 may be 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 may be used simultaneously, or a mouse and finger contacts may be used simultaneously. 
     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 . 
       FIG. 5A  illustrates document  500  displayed on touch screen  112  of device  100 . Document  500  may be displayed in the user interface of an application (e.g., a word processing application, a presentation application, a spreadsheet application, etc.). The application user interface in which document  500  is displayed may include toolbar  510  and “documents” button  512  for navigating to, if any, other documents. In some embodiments, document  500  is displayed in a document viewing or navigating mode. 
     Document  500  includes content, such as text  502 , images, objects, tables, charts, and so on. Text  502  has a respective font size. In some embodiments, text  502  includes multiple portions with respective, different font sizes. Document  500  has a predefined page layout; the content in document  500  is laid out in a predefined way and the layout is not affected by changes in the magnification level at which document  500  is displayed on touch screen  112 . 
     Document  500  is displayed at a first magnification level. For example, as shown in  FIG. 5A , the first magnification level may be one that corresponds to fitting a whole page of document  500  on display  112 . Document  500  may also be displayed at a larger or smaller magnification (e.g., in response to user input). Text  502 , for the same font size, has a text display size on screen that varies with the magnification level. Thus, text  502  has a first display size at the “fit whole page” magnification level. The text display size is the size of the text as it appears on the display of a device (e.g., touch screen  112  of device  100 ), as opposed to the font size, which is the size of the text as it would appear if printed out on physical media (e.g., paper). 
     In some embodiments, the magnification level is expressed as a percentage (e.g., 100%, 200%, 50%, etc.). The fit whole page magnification level described above corresponds to a magnification level percentage that achieves the fitting of a whole page onto display  112 . 
     Gesture  504  is detected at a location on touch screen  112  corresponding to a location on document  500 . In some embodiments, gesture  504  is a single tap gesture. The location of gesture  504  indicates insertion point  506  in text  502 . Insertion point  506  is proximate to text portion  508  of text  502 . 
       FIG. 5B  shows, alternatively, gesture  514  detected at a location on touch screen  112  corresponding to a location on document  500 . In some embodiments, gesture  514  includes a tap and hold of a finger contact (i.e., finger makes contact on touch screen  112  and maintains contact with touch screen  112 , followed by a later liftoff of the contact). In response to the detection of gesture  514 , loupe  516  is displayed, showing a magnified view of text portion  508  and insertion point marker  518  indicating an insertion point at a location in text  502  that corresponds to the location of gesture  514 . While gesture  514  is active (i.e., contact with touch screen  112  is maintained), insertion point marker  518  may be moved across document  500  (e.g., by moving the finger across touch screen  112 ) and loupe  516  follows the movement of insertion point marker to show a magnified view of the text in proximity to insertion point marker  518 . 
     In response to the detection of gesture  504  or  514  and the completion of the respective gesture (e.g., when the finger contact of gesture  504  or  514  is lifted up from touch screen  112 ), portion  520  of document  500  is displayed in document editing mode, as shown in  FIG. 5C . While in document editing mode, document  500  (including portion  520 ) is displayed at a second magnification level that is different from the first magnification level. Document portion  520  includes text portion  508 . In some embodiments, the second magnification level is a magnification level at which text portion  508  is displayed on touch screen  112  at a text display size that is comfortable for reading. For example, if text portion  508  has a font size whose text display size at 100% magnification is not comfortable for reading on touch screen  112 , text portion  508  may be displayed, when in document editing mode, at 200% magnification. 
     Insertion point marker  518  is displayed at the insertion point (e.g., insertion point  506 ), and text portion  508  is proximate (e.g., adjacent) to insertion point marker  518 . In some embodiments, insertion point marker  518  is a text cursor. 
     Document portion  520  is displayed such that the predefined layout of document  500  is maintained; text  502 , including text portion  508  is not re-flowed, re-wrapped, or the like. While in document editing mode, document  500  is scrollable (e.g., in response to swipe or flick gestures on touch screen  112 ). 
     While document portion  520  is displayed in document editing mode, keyboard  521  is also displayed, and “documents” button in toolbar  510  is replaced by “done” button  522 . A user may enter text into document  500  by typing on keyboard  521 , and confirm completion of editing of document  500  by performing a gesture (e.g., a tap gesture) on “done” button  522 . When “done” button  522  is activated by performance of a gesture on “done” button  522 , the document editing mode ends and a document viewing mode resumes. For example,  FIG. 5D  shows gesture  524  detected on touch screen  112  at a location corresponding on “done” button  522  (gesture  524  may be said to be detected on “done” button  522 ). 
     In response to the detection of gesture  524 , document  500 , including the revisions entered and confirmed in document editing mode, is displayed at the fit whole page magnification level and in a document viewing mode, as shown in  FIG. 5E . “Done” button  522  is replaced by “documents” button  512  in toolbar  510 . 
       FIG. 5F  shows document  500 , with text  502 , displayed in document viewing mode, along with toolbar  510  and “documents” button  512 . Document  500  is displayed at fit whole page magnification; text  502  is displayed at a text display size corresponding to the fit whole page magnification level. 
     Gesture  526  is detected at a location on touch screen  112  corresponding to a location on document  500 . In some embodiments, gesture  526  is a single tap gesture. The location of gesture  526  indicates insertion point  506  in text  502 . Insertion point  506  is proximate to text portion  508  of text  502 . 
     In response to the detection of gesture  526 , document portion  520  of document  500  is displayed in document editing mode, as shown in  FIG. 5G . Document portion  520  includes text portion  508 . Document portion  520  is displayed at a magnification level such that text portion  508  is displayed at a default target text display size. Keyboard  521  is also displayed, and “documents” button  512  is replaced by “done” button  522 . Insertion point marker  518  is displayed to mark insertion point  506 . 
     Gesture  534  is detected on touch screen  112 . Gesture  534  is a gesture to adjust the magnification level at which document portion  520  is displayed. In some embodiments, gesture  534  is a depinch gesture, with contacts  534 -A and  534 -B moving apart. In response to the detection of gesture  534 , document portion  520  is displayed, while remaining in document editing mode, at a user-adjusted magnification level, as shown in  FIG. 5H , which in this case is larger than the magnification level as shown in  FIG. 5G . Accordingly, text portion  520  is displayed at a user-adjusted text display size, which in this case is larger than the default target text display size as shown in  FIG. 5G . The user-adjusted text display size is stored by device  100 . 
     While text portion  508  is displayed at the user-adjusted text display size, gesture  536  is detected on “done” button  522 , as shown in  FIG. 5H . In response to the detection of gesture  536  on “done” button  522 , document  500 , including the revisions entered and confirmed in document editing mode, is displayed at the fit whole page magnification level and in a document viewing mode, as shown in  FIG. 5I . “Done” button  522  is replaced by “documents” button  512  in toolbar  510 . 
     In  FIG. 5I , while document  500  is displayed in document viewing mode and at the fit whole page magnification level, gesture  536  is detected at a location on touch screen  112  corresponding to a location on document  500 . In some embodiments, gesture  536  is a single tap gesture. The location of gesture  536  indicates insertion point  538  in text  502 . Insertion point  538  is proximate to text portion  540  of text  502 . 
     In response to the detection of gesture  536 , document portion  541  of document  500 , which includes text portion  540 , is displayed in document editing mode, as shown in  FIG. 5J . Document portion  541  is displayed at a magnification level such that text portion  540  is displayed at the user-adjusted text display size that was stored previously. Insertion point marker  518  is displayed to mark insertion point  538 . Despite document portion  541  being a different portion of document  500  than document portion  520  (and text portion  540  being different from text portion  508 ), document portion  541  is displayed at a magnification level such that text portion  540  is displayed at the user-adjusted text display size. 
       FIG. 5K  illustrates document  542 , which includes text  543 , being displayed in document viewing mode on touch screen  112 . Document  542  includes document portions  544  and  546 . The text (a portion of text  543 ) in document portion  544  and the text (another portion of text  543 ) in document portion  546  have different font sizes. At a given magnification level at which document  542  is displayed, the text display size of text in document portion  544  is larger than the text display size of text in document portion  546 . 
     Gesture  548  is detected at a location on touch screen  112  corresponding to a location on document  542 . In some embodiments, gesture  548  is a single tap gesture. The location of gesture  548  indicates insertion point  550  in text  543 . Insertion point  550  is proximate to text portion  552  of text  543 . Text portion  552  is located in document portion  546 . 
     In response to the detection of gesture  548 , document portion  546  is displayed in document editing mode, as shown in  FIG. 5L . Document portion  546  is displayed at a certain magnification level. Accordingly, text portion  552  is displayed at a target text display size. Insertion point marker  518  is displayed to mark insertion point  550 . Also displayed is keyboard  521 . 
       FIG. 5M  shows document portion  544 , which includes text portion  556  of text  543 , displayed on touch screen  112  in document editing mode. Document portion  544  may be reached from document portion  546  as displayed in  FIG. 5L  by scrolling document  542  (e.g., using swipe gestures). Alternatively, document portion  544  may be reached from document portion  546  as displayed in  FIG. 5L  by dragging insertion marker  518  from document portion  546  to document portion  544  while in document editing mode. Document portion  544  is displayed at the same magnification level as document portion  546  is displayed in  FIG. 5L . Text portion  556  is displayed at a larger text display size than text portion  552  is displayed in  FIG. 5L . Text portion  556  has a larger font size than text portion  552  and thus has a larger text display size for the same magnification level. 
     Gesture  554  is detected at a location on touch screen  112  corresponding to a location in document portion  544 . In some embodiments, gesture  554  is a single tap gesture. The location of gesture  554  indicates insertion point  555  in text  544 . Insertion point  555  is proximate to text portion  556  of text  544 . 
     In response to the detection of gesture  554 , as shown in  FIG. 5M , document portion  544  is displayed in  FIG. 5N  at a lower magnification level than that shown in  FIG. 5M . Insertion point marker  518  is displayed to mark insertion point  555 . At this lower magnification level, text portion  556  is displayed at the same text display size as text portion  552  is displayed in  FIG. 5L ; the magnification level of the document is changed such that text of different font sizes are displayed at the same text display size as the user navigates from text of one font size to text of a different font size. 
       FIG. 5O  illustrates a portion of document  558  being displayed, in document editing mode, at a certain magnification level. Text in document  558  is displayed at a certain text display size. Text  562  is selected, as indicated by content selection range  560 . Also displayed are selection options menu  565  for manipulating the selected text  562 , and content selection handles  564 -A and  564 -B for adjusting content selection range  560 . Gesture  566  is detected on handle  564 -B, dragging handle  564 -B in a direction that increases content selection range  560  (e.g., downward in  FIG. 5O ). 
     In response to the detection of gesture  566 , selection range  560  is enlarged, as shown in  FIG. 5P . In some embodiments, loupe  567 , which shows a magnified view of text at the end of selection range  560  as handle  564 -B is moved, is displayed. 
     With the enlarged content selection range  560 , selected text  562  includes more text than is shown in  FIG. 5O . Some of selected text  562  is not displayed in  FIG. 5O . 
       FIG. 5Q  illustrates gesture  566  ceasing to be detected on touch screen  112 , while selection range  560  includes an end of a paragraph in document  558 . With the ceasing (lift off) of gesture  566 , adjustment of content selection range  560  is completed. In response to detecting completion of gesture  566 , the magnification level at which document  558  is displayed is changed, as shown in  FIG. 5R . The new magnification level is chosen so that the entirety of selected text  562  in content selection range  560  is displayed on touch screen  112 , rather than showing just some of selected text  562  because the magnification level is too high. For example, document  558  may be displayed at a fit whole page magnification level, as shown in  FIG. 5R , or a fit page width magnification level. 
     Also shown in  FIG. 5R , content selection range  560  is extended so that selected text  562  includes an entire paragraph. Also displayed are paragraph selection options menu  569  for manipulating the selected paragraph, and handles  564 -A and  564 -B for adjusting selection range  560 . As shown in  FIG. 5R , handles  564 -A and  564 -B may be dragged to adjust selection range  560  to select more paragraphs or less paragraphs; a paragraph becomes the unit of text selection, as opposed to a smaller unit such as a character or a word. 
     In  FIG. 5R , gesture  568  is detected on handle  564 -B, which drags handle  564 -B downward, toward another paragraph of text in document  558 . In response to the detection of gesture  568 , selection range  560  is extended by a paragraph, and selected text  562  includes another paragraph, as shown in  FIG. 5S . 
       FIG. 5T  shows document  570  displayed in document viewing mode on touch screen  112 . Document  570  includes objects  572  and  576 . In some embodiments, an object is a shape, image, or other graphical object. Object  572  includes editable text  574 , and object  576  does not include editable text. 
     When a gesture is detected on object  576  (e.g., gesture  580 , which may be a single tap gesture, on object  576 ,  FIG. 5T ), object  576  is displayed in document editing mode, at a magnification level that achieves a particular object display size, as shown in  FIG. 5U . The object display size is the size of the object as is appears on the display. In some embodiments, that particular object display size is a predefined size with respect to touch screen  112 . For example, the predefined size may be a size that fits the entire object  576  onto touch screen  112 . 
     In contrast, when a gesture is detected on object  572  (e.g., gesture  582 , which may be a single tap gesture,  FIG. 5T ), object  572  is displayed in document editing mode, at a magnification level that achieves a particular text display size for text  574 , as shown in  FIG. 5V . This magnification level may be selected without reference to the size of object  572 . In some embodiments, that particular text display size is a default text display size or a previously-stored user-adjusted text display size. Thus, when a gesture (e.g., a single tap gesture) is detected on an object, if the object includes editable text, the new magnification level accommodates the text, and if the object does not include editable text, the new magnification level accommodates the object. 
       FIG. 5W  illustrates document  584  being displayed, in document viewing mode, on touch screen  112 . Document  584  is a spreadsheet document and includes worksheet  591 . Worksheet  591  includes one or more rows and one or more columns. Document  582  is displayed at some magnification level. Also displayed are toolbar  586  and “spreadsheets”  588  for navigating to other spreadsheet documents, similar to “documents” button  512 . 
     Gesture  590 , for changing the magnification level of document  584 , is detected on touch screen  112 . Gesture  590  includes contacts  590 -A and  590 -B moving apart (i.e., gesture  590  is a depinch gesture). In response to the detection of gesture  590 , document  584  is displayed, still in the document viewing mode, at a user-adjusted magnification level, as shown in  FIG. 5X . 
     Gesture  592  is detected on touch screen  112 , in proximity of cell  594  in worksheet  591 . In some embodiments, gesture  592  is a double tap gesture. Cell  594  becomes the insertion point. In response to the detection of gesture  592 , document  584  is displayed in a document editing mode, as shown in  FIG. 5Y . Document  584  is displayed at a magnification level different from the user-adjusted magnification level. Cell  594 , as the cell that is in proximity to gesture  592 , becomes an editable cell and in focus (e.g., centered) and is highlighted by cell insertion point marker  593 . Also displayed are keypad  595 , edit field  596  showing the current contents of cell  594 , and edit complete button  597 . A user may enter edits into the contents of cell  594  using keypad  595 , and the edits are reflected in edit field  596 . 
     When editing is completed, a user activates edit complete button  597  with a gesture. For example, gesture  598  is detected on edit complete button  597 , as shown in  FIG. 5Z . In some embodiments, gesture  598  is a single tap gesture. In response to the detection of gesture  598  on edit complete button  597 , document  584  is displayed at the user-adjusted magnification level (the same level as in  FIG. 5X ), as shown in FIG.  5 AA. Edit field  596  ceases to be displayed, and in worksheet  591 , cell selection marker  599  is displayed instead of cell insertion point marker  593 . 
       FIGS. 6A-6E  are flow diagrams illustrating a method  600  of navigating and editing an electronic document in accordance with some embodiments. The method  600  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1 ) with a display and, typically, 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  600  may be combined and/or the order of some operations may be changed. 
     As described below, the method  600  provides an intuitive way to automatically zoom in on a user-specified insertion point when entering a document editing mode and display the text at the insertion point at a target text display size for easy viewing and editing. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays at least a portion of an electronic document with a predefined page layout at a first magnification level on the display ( 602 ). In other words, the electronic document has a fixed page layout and the text does not “reflow” as the magnification level of the document is changed. For example, in  FIG. 5A , document  500  with predefined page layout is displayed on touch screen  112 . In  FIG. 5A , document  500  is displayed at the fit whole page magnification level. 
     In some embodiments, the predefined page layout is a multi-page layout and the document has content that is associated with a plurality of the pages (e.g., the electronic document is a word processor document, presentation document, pdf, etc.) ( 604 ). For example, document  500  may have one or more pages in addition to the one displayed in  FIG. 5A . 
     In some embodiments, the predefined page layout is a table with a plurality of rows and a plurality of columns (e.g., the electronic document is a spreadsheet document, etc.) ( 606 ). 
     The device detects a first input indicating a first insertion point in the document, where the first insertion point is proximate to (e.g., adjacent to) a first portion of text in the document ( 608 ). The first portion of text is typically a word or character adjacent to the first insertion point that has a predefined font size (e.g., a font size specified by the document). For example, in  FIG. 5A  gesture  504  is detected. The location of gesture  504  indicates the insertion point  506 . In some embodiments, the gesture is a finger gesture (e.g., a tap gesture) that has a contact area and the centroid of the contact area (or a point offset from the centroid of the contact area) is used to locate the insertion point. Insertion point  506  is proximate to text portion  508 . 
     It should be understood that, as used herein, the term “insertion point” refers to a location within the document that may also used as a location for displaying an insertion point marker, such as a text cursor or highlighted word. 
     In response to detecting the first input ( 610 ), the device selects a second magnification level different from the first magnification level, where the second magnification level is selected so as to display the first portion of text at a target text display size ( 612 ); and, while maintaining the predefined page layout of the document, the device displays, at the second magnification level, a portion of the document that includes the first portion of text ( 614 ). For example, in  FIGS. 5A  thru  5 C, in response to the detection of gesture  504  ( FIG. 5A ) or gesture  514  ( FIG. 5B ), document portion  520 , which includes text portion  508 , is displayed at a larger magnification level, where the larger magnification level is one that is selected so that text portion  508  is displayed at a text display size that is comfortable for reading. 
     In other words, a magnification level is selected such that text is displayed at a target text display size that has been determined to be a comfortable reading size (e.g., 17 pt or some other predefined text display size). 
     It should be understood that the target text display size may be either a predefined target text display size or a user-adjusted target text display size, as described below in greater detail with reference to method  700  and  FIGS. 7A-7B . 
     It should be understood that, as used in the specification and claims, “text display size” is different from “font size.” In particular, as used herein, the “font size” of the text corresponds to a physical dimension of the text as it would appear if the document were to be printed out. In contrast, “text display size” corresponds to a dimension of the text as it appears on the display of the electronic device and is not necessarily the physical dimension of the text as it would appear when printed. Thus, the text display size of a word may be substantially larger or substantially smaller than the font size, depending on the magnification level at which the document is displayed. For example, a word with font size of 12 pt in a document could be displayed at a text display size of 24 pt by displaying the document at a 200% magnification level. 
     In some embodiments, displaying the portion of the document at the second magnification level includes displaying an animation of the document zooming from the first magnification level to the second magnification level ( 616 ). For example, there may be an animated transition from the magnification level shown in  FIG. 5A  to the magnification level as shown in  FIG. 5C . 
     In some embodiments, in response to detecting the first input, the device performs an operation selected from the set consisting of: placing a text cursor at the first insertion point, selecting a cell of a spreadsheet proximate to the first insertion point for editing, and highlighting text proximate to the first insertion point ( 618 ). For example, in response to the detection of gesture  504  ( FIG. 5A ), insertion point marker  518  is inserted at insertion point  506  ( FIG. 5C ). 
     In some embodiments, in response to detecting the first input, the device scrolls the document so that the first insertion point is in a central region of a displayed portion of the document ( 620 ). In some embodiments, the document is scrolled in one dimension (e.g., horizontally or vertically). In some embodiments, the document is scrolled or translated in two dimensions (e.g., horizontally and vertically). For example, in  FIG. 5C , insertion point marker  518  (marking insertion point  506 ) is approximately centered in the displayed part of document portion  520 . Scrolling of document  500  may be needed, when transitioning from the magnification level shown in  FIG. 5A  to the magnification level shown in  FIG. 5C , to achieve the centering. 
     In some embodiments, the electronic device includes a touch-sensitive surface, and the first input is detected on the touch-sensitive surface ( 622 ). In some embodiments, the touch-sensitive surface is separate from the display. In some embodiments, the touch-sensitive surface and the display are combined as a touchscreen display. For example, display  112  on device  100  is a touch screen, and gesture  504  is detected on touch screen  112 . 
     In some embodiments, the first input is a single tap on the touch-sensitive surface ( 624 ). For example, gesture  504  ( FIG. 5A ) may be a single tap gesture. 
     In some embodiments, the electronic device includes a touch-sensitive surface, and the first input includes detecting a contact on the touch-sensitive surface, detecting movement of the contact on the touch-sensitive surface, and ceasing to detect the contact on the touch-sensitive surface ( 626 ). For example, in  FIG. 5B , gesture  514  includes a contact on touch screen  112 , any movement as needed to move insertion point marker  518  to the desired insertion point location, and liftoff of the contact from touch screen  112 . 
     In some embodiments, while detecting movement of the contact on the touch-sensitive surface, the device displays a magnified portion of the document corresponding to a current location of the contact on the touch-sensitive surface, where the first insertion point is selected based on a position of the contact on the touch-sensitive surface when the device ceases to detect the contact on the touch-sensitive surface ( 628 ). In some embodiments, the magnified portion of the document has the appearance of a loupe and enables more accurate selection of the first insertion point. For example, in  FIG. 5B , loupe  516  is displayed. Loupe  516  shows a magnified view of text  508  around insertion point marker  518 , which is located at a location in document  500  corresponding to the location of the contact of gesture  514 . The location of insertion point marker  518  is confirmed when the contact of gesture  514  lifts off from touch screen  112 . 
     In some embodiments, in response to detecting the first input, the device enters a document-editing mode ( 630 ). For example, in  FIG. 5C , in response to gesture  504  or  514 , document portion  520  is displayed in document editing mode. Keyboard  521  is displayed, and “documents” button  512  is replaced by “done” button  522 . Thus, a single input (e.g., a tap gesture or a tap and hold gesture) results in: entering edit mode, placing a text cursor, zooming to a different magnification level with a comfortable text display size, scrolling the document to place the insertion point in a central region of the display, and displaying a soft keyboard. 
     In some embodiments, the electronic device enters the document-editing mode in response to detecting an end of the first input (e.g., when the display is a touchscreen display, detecting the end of the input is typically detecting liftoff of a contact from the touchscreen display) ( 632 ). For example, document  500  is displayed in document editing mode (as in  FIG. 5C ) in response to the end of gesture  504  or  514 . 
     In some embodiments, in response to detecting the first input, the device displays a soft keyboard on the display ( 634 ). For example, in response to gesture  504 , along with the display of document  500  in document editing mode, keyboard  521  is displayed ( FIG. 5C ). 
     In some embodiments, while in the document-editing mode, the device edits text of the document in response to user inputs ( 636 ). For example, in  FIG. 5C-5D , text portion  508  may be edited in response to user typing on keyboard  521 . 
     In some embodiments, the document is one of a plurality of documents ( 638 ). Prior to entering the document-editing mode, the device displays a navigation affordance (e.g., documents button) for navigating between different documents in a set of documents ( 640 ). After entering the document-editing mode, the device replaces the navigation affordance with an exit affordance (e.g., done button) for exiting the document-editing mode ( 642 ). For example, In  FIG. 5A , “documents” button  512  is displayed. In  FIG. 5C , when document  500  is displayed in document editing mode, “documents” button  512  is replaced by “done” button  522 . 
     In some embodiments, the device receives a request to exit the document-editing mode ( 644 ); and, in response to receiving the request to exit the document-editing mode ( 646 ), exits the document-editing mode ( 648 ) and displays the document at the first magnification level. (e.g., returns to prior magnification level) ( 650 ). For example, in  FIG. 5D , gesture  524  is detected on “done” button  522 . In response to the detection of gesture  524  on “done” button  522 , document  500  is displayed in document viewing mode at fit whole page magnification (as shown in  FIG. 5E ), which is the same magnification level as in  FIG. 5A . 
     In some embodiments, the device receives a request to exit the document-editing mode ( 652 ); and, in response to receiving the request to exit the document-editing mode ( 654 ), exits the document-editing mode ( 656 ) and displays the document at a third magnification level that corresponds to a predefined document magnification level different from the first magnification level (e.g., a page width magnification level) ( 658 ). For example, in  FIG. 5D , gesture  524  is detected on “done” button  522 . In response to the detection of gesture  524  on “done” button  522 , document  500  may be displayed at a magnification level different than the magnification level shown in  FIG. 5A  (not shown). 
     In some embodiments, while in the document-editing mode, the device scrolls the document in response to detecting inputs from a user ( 660 ); and, after exiting the document-editing mode, redisplays the document as it appeared when the first input was detected ( 662 ). In other words, the document is scrolled and zoomed so as to reposition the document at the same magnification level and scroll position that it was displayed at prior to entering the edit mode. It should be understood that the document may be scrolled in one or two dimensions while in edit mode. For example, in  FIG. 5C , document  500  is scrollable while in document editing mode. After exiting document editing mode in response to detection of gesture  524 , document  500  is displayed at the same magnification level as when gesture  504  is detected in  FIG. 5A . 
     In some embodiments, the target text display size at which the first portion of text is displayed in response to detecting the first input is a default target text display size ( 664 ). While displaying the portion of the document that includes the first portion of text at the second magnification level, the device detects a second input corresponding to a request to display a portion of the document at a third magnification level different from the second magnification level ( 666 ). In response to detecting the second input ( 668 ), the device displays the portion of the document at the third magnification level ( 670 ) and stores a user-adjusted target text display size corresponding to a text display size of the first portion of text at the third magnification level ( 672 ), where the user-adjusted target text display size is different from the default target text display size. After storing the user-adjusted target text display size ( 674 ), the device detects a third input indicating a second insertion point in the document, where the second insertion point is proximate to a second portion of text in the document ( 676 ); and in response to detecting the third input, displays the document at a respective magnification level such that the second portion of text is displayed at the user-adjusted target text display size ( 678 ). For example, in  FIGS. 5C and 5G , text portion  508  is displayed at a text display size that may be a default text display size as a result of document portion  520  being displayed at the second magnification level. In  FIG. 5G , gesture  534  to adjust the magnification level is detected. In response to the detection of gesture  534 , document portion  520  is displayed at a user-adjusted magnification level (as shown in  FIG. 5H ), and a text display size corresponding to the user-adjusted magnification level is stored. Subsequently, gesture  536  ( FIG. 5I ) indicating insertion point  538  is detected. In response to the detection of gesture  536 , document portion  541  is displayed at the user-adjusted magnification level so that text portion  540  is displayed at the stored text display size (instead of the prior default text display size in  FIGS. 5A and 5G ), as shown in  FIG. 5J . 
     In some embodiments, the first portion of text has a first font size ( 680 ). While displaying the portion of the document that includes the first portion of text at the second magnification level, the device detects a second input indicating a second insertion point in the document ( 682 ), where the second insertion point is proximate to a second portion of text in the document, and the second portion of text has a second font size different from the first font size. In response to detecting the second input ( 684 ), the device selects a third magnification level different from the second magnification level ( 686 ), where the third magnification level is selected so as to display the second portion of text at the target text display size, and displays a portion of the document at the third magnification level ( 688 ). For example, text portion  508  has a font size, and is displayed at a text display size ( FIG. 5C ). A gesture indicating another insertion point proximate to a text portion with a different font size, analogous to gesture  554  ( FIG. 5M ), may be detected. In response to the gesture, text in the text portion with the different font size is displayed at a certain magnification level so that that text is displayed at a same text display size as text portion  508 . 
     In some embodiments, after displaying the portion of the document that includes the first portion of text at the second magnification level ( 690 ), the device detects a content selection input ( 692 ). In response to detecting the content selection input ( 694 ), the device identifies a selected portion of the document in accordance with the content selection input ( 696 ), and in accordance with a determination that the selected portion of the document includes content that is outside of a currently displayed portion of the document, the device adjusts display of the document so that the entire selected portion of the document is displayed on the display ( 698 ). For example, a content selection input similar to gesture  566  ( FIG. 5O ) on content selection handle  564 -B may be detected. In response to the detection of gesture  566 , text in document  500  may be selected. If the selected text includes portion outside of a currently displayed portion, the magnification level of document  500  may be adjusted to display the entire selected text. 
     It should be understood that the particular order in which the operations in  FIGS. 6A-6E  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 methods  700 ,  800 ,  900 ,  1000 , and  1100  (e.g.,  FIGS. 7A-7B ,  8 A- 8 B,  9 A- 9 B,  10 , and  11 A- 11 B, respectively) are also applicable in an analogous manner to method  600  described above with respect to  FIGS. 6A-6E . For example, the electronic document, insertion point and various magnification levels described above with reference to method  600  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  700 ,  800 ,  900 ,  1000 , and  1100 . For brevity, these details are not repeated here. 
       FIGS. 7A-7B  are flow diagrams illustrating a method  700  of navigating and editing an electronic document 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. 1 ) with a display and a, typically, 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  may be combined and/or the order of some operations may be changed. 
     As described below, the method  700  provides an intuitive way to modify the target text display size from a default value to a user-adjusted value. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays at least a portion of an electronic document at a first magnification level on the display ( 702 ). For example, in  FIG. 5F , document  500  is displayed at a fit whole page magnification level. 
     In some embodiments, the document has a predefined page layout and the predefined page layout is maintained while displaying the document at different magnification levels ( 704 ). 
     The device detects a first input indicating a first insertion point in the document, wherein the first insertion point is proximate to a first portion of text in the document ( 706 ). For example, in  FIG. 5F , gesture  526  is detected. The location of gesture  526  indicates insertion point  506 , which is proximate to text portion  508 . 
     In response to detecting the first input ( 708 ), the device selects a second magnification level different from the first magnification level, where the second magnification level is selected so as to display the first portion of text at a default target text display size ( 710 ), and displays a portion of the document at the second magnification level ( 714 ). For example, in  FIG. 5G , in response to detecting gesture  526 , document portion  520  is displayed at a different magnification level from the fit whole page magnification level shown in  FIG. 5F . The different magnification level is one that is selected by device  100  such that text portion  508  (adjacent to the insertion point) is displayed at a default target text display size. 
     In some embodiments, the default target text display size is a predefined value in the range 10 pt-24 pt ( 712 ). 
     The device detects a second input corresponding to a request to display a portion of the document at a third magnification level different from the second magnification level ( 716 ). For example, in  FIG. 5G , depinch gesture  534  to change the magnification level is detected. 
     In response to detecting the second input ( 718 ), the device displays the portion of the document at the third magnification level ( 720 ), and stores a user-adjusted target text display size corresponding to a text display size of the first portion of text (e.g., the text adjacent to the first insertion point) at the third magnification level, where the user-adjusted target text display size is different from the default target text display size ( 722 ). For example, in response to the detection of gesture  534 , document portion  520  is displayed at yet another magnification level ( FIG. 5H ). At this user-adjusted magnification level, text portion  508  has a particular text display size. This text display size is stored as a user-adjusted target text display size. 
     In some embodiments, the user-adjusted target text display size is only stored when the text display size of the first portion of text meets predefined text display size criteria (e.g., in accordance with a determination that the text display size of the first portion of text is within a range of values that are “allowable” target text display sizes). In other words, the input is ignored for the purposes of storing a user-adjusted target display size if the user zooms to a magnification level at which text is either too large (e.g., greater than 72 pt) or too small (e.g., smaller than 10 pt) for a typical user to comfortably read, because the user is likely zooming the document for some purpose other than editing text proximate to the insertion point. 
     After storing the user-adjusted target text display size ( 724 ), the device detects a third input indicating a second insertion point in the document, where the second insertion point is proximate to a second portion of text in the document ( 726 ), and, in response to detecting the third input, displays the document at a respective magnification level such that the second portion of text is displayed at the user-adjusted target text display size ( 730 ). It should be understood that the first portion of text may be the same as or different from the second portion of text. For example, in  FIG. 5I , gesture  536  is detected. Gesture  536  indicates insertion point  538 , which is proximate to text portion  540 . In response to the detecting gesture  536 , document portion  541  is displayed at a magnification level such that text portion  540  is displayed at the stored user-adjusted target text display size ( FIG. 5J ). 
     It should be understood that this process could be repeated any number of times to set a new user-adjusted target text display size. However, typically, a user will determine a preferred target text display size and thus the user will not need to continually adjust the user-adjusted target text display size. Rather, the user will find that the target text display size used for the whole document (or set of documents) is the user&#39;s preferred target text display size, which will improve user efficiency and enhance user productivity. 
     In some embodiments, the user-adjusted target text display size is ignored or discarded when the user-adjusted target text display size is not within predefined text display size criteria. Optionally, the predefined text display size criteria include an upper bound (e.g., a text display size between 48 pt-80 pt) and a lower bound of (e.g., a text display size between 10 pt-18 pt). Thus, in these embodiments, when the text display size of the first portion of text at the third magnification level is outside of the predefined text display size criteria (e.g., above the upper bound or below the lower bound), the device continues to use the default target text display size or the last user-adjusted target text display size that was within the predefined text display size criteria. For example, if a user zooms out to display a whole page (e.g., at 4 pt text display size) of a document in a document-editing mode immediately prior to exiting the document-editing mode, the device either reverts to the default target text display size (e.g., 17 pt) or a prior user-adjusted target text display size (e.g., 15 pt). Thus, in this example, when the device re-enters document-editing mode, the device displays the document at a respective magnification level such that the respective portion of text is comfortably readable (e.g., 17 pt or 15 pt rather than 4 pt). 
     In some embodiments, the first portion of text is different from the second portion of text ( 728 ). For example, text portion  508  ( FIG. 5H ) is different from text portion  540  ( FIG. 5J ). In other words, the user-adjusted target text display size may be used as a target text display size for many different locations within the same document. 
     In some embodiments, the device uses the user-adjusted target text display size as a target display size for a plurality of different documents accessible by the device ( 736 ). In other words, the user-adjusted target text display size may also be used as a target text display size for many different documents on the device. 
     In some embodiments, the respective magnification level is the same as the third magnification level if the second portion of text has a same font size as the first portion of text ( 732 ). In other words, when the cursor moves between text with the same font size, the document is not zoomed to a different magnification level. 
     In some embodiments, the respective magnification level is different from the third magnification level if the second portion of text has a different font size from a font size of the first portion of text ( 734 ). In other words, when the cursor moves between text with different font sizes, the document is zoomed to a different magnification level. 
     In some embodiments, after storing the user-adjusted target text display size and prior to detecting a third input indicating the respective insertion point in the document, the device exits a document-editing mode and displays the document at the first magnification level ( 738 ). For example, in  FIG. 5H , after the user-adjusted target text display size is stored, gesture  536  is detected on “done” button  522 . In response to the detection of gesture  536 , document  500  is displayed again at the magnification level in  FIG. 5F , as shown in  FIG. 5I . 
     It should be understood that the particular order in which the operations in  FIGS. 7A-7B  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 methods  600 ,  800 ,  900 ,  1000 , and  1100  (e.g.,  FIGS. 6A-6E ,  8 A- 8 B,  9 A- 9 B,  10 , and  11 A- 11 B, respectively) are also applicable in an analogous manner to method  700  described above with respect to  FIGS. 7A-7B . For example, the electronic document, insertion point and various magnification levels described above with reference to method  700  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  600 ,  800 ,  900 ,  1000 , and  1100 . For brevity, these details are not repeated here. 
       FIGS. 8A-8B  are flow diagrams illustrating a method  800  of navigating and editing an electronic document 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. 1 ) with a display, typically, 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  may be combined and/or the order of some operations may be changed. 
     As described below, the method  800  provides an intuitive way to automatically adjust the display magnification to maintain a target text display size as the insertion point is moved between areas in a document with different font sizes. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays at least a portion of an electronic document at a first magnification level on the display ( 802 ). For example, in  FIG. 5K , document  542  is displayed at some magnification level on touch screen  112 . 
     In some embodiments, the electronic document has a predefined page layout and the predefined page layout is maintained while displaying the document at different magnification levels ( 804 ). For example, document  542  has a predefined layout that is maintained across different magnification levels. 
     The device detects a first input indicating a first insertion point in the document ( 806 ), where the first insertion point is proximate to a first portion of text in the document, the first portion of text having a first font size. Alternatively, the first font size is a font size at the insertion point (e.g., when there is an insertion point marker such as a text cursor, the first font size is a font size that would be used for text entered at the text cursor). For example, in  FIG. 5K , gesture  548  is detected. The location of gesture  548  indicates insertion point  550 , which is in proximity to text portion  552 . 
     In response to detecting the first input ( 808 ), the device selects a second magnification level different from the first magnification level, where the second magnification level is selected so as to display the first portion of text at a target text display size ( 810 ); and displays a portion of the document at the second magnification level ( 812 ). For example, in  FIG. 5L , in response to the detection of gesture  548  ( FIG. 5K ), document portion  546  is displayed at a magnification level different from the level at which document  542  is displayed in  FIG. 5K . The magnification level at which document portion  546  is displayed in  FIG. 5L  is selected so that text portion  552  is displayed at a target text display size. 
     It should be understood that the target text display size is a predefined target text display size (e.g., either a default target text display size or a previously stored user-adjusted target text display size, as described in greater detail above with reference to method  700  and  FIGS. 7A-7B ). 
     While displaying the portion of the document at the second magnification level, the device detects a second input indicating a second insertion point in the document ( 814 ), where the second insertion point is proximate to a second portion of text in the document, the second portion of text having a second font size different from the first font size. For example, in  FIG. 5M , gesture  554  is detected. Gesture  554  indicates insertion point  555 , which is in proximity to text portion  556  in document portion  544 . Text in document portion  544 , including text portion  556 , have a different font size from text portion  552  ( FIG. 5L ). The second input may include, in addition to gesture  554 , gestures to scroll from document portion  546 , where text portion  552  is located, to document portion  544 . 
     In some embodiments, the first font size is larger than the second font size ( 816 ). 
     In some embodiments, the first font size is smaller than the second font size ( 818 ). 
     In response to detecting the second input ( 822 ), the device selects a third magnification level different from the second magnification level ( 824 ), where the third magnification level is selected so as to display the second portion of text at the target text display size; and displays a portion of the document at the third magnification level ( 826 ). For example, in response to detection of gesture  554  ( FIG. 5M ), document portion  544  is displayed at a different magnification level ( FIG. 5N ), such that text portion  556  is displayed at the same text display size as text portion  552  is displayed (the target text display size) in  FIG. 5L . 
     In some embodiments, if the difference between first font size and second font size is below a predefined threshold (e.g., &lt;3 pt difference), in response to detecting the second input, the device maintains display of the document at the second magnification level (e.g., so as to prevent frequent small changes to the magnification level of the document that could appear as unnecessary jitter to a user). 
     In some embodiments, the second input is a find command or a replace command ( 820 ). In other words, as the device switches from one occurrence of a term to a next occurrence of the term in the document, the device changes the magnification level at which the document is displayed in accordance with a font size of the next occurrence of the term in the document. 
     In some embodiments, the electronic device includes a touch-sensitive surface, and the first input and the second input are detected on the touch-sensitive surface ( 828 ). In some embodiments, the second input is a single tap on the touch-sensitive surface ( 830 ). In some embodiments, the touch-sensitive surface is separate from the display. In some embodiments, the touch-sensitive surface and the display are combined as a touchscreen display. For example, gestures  550  and  554  are detected on touch screen  112 . 
     It should be understood that the particular order in which the operations in  FIGS. 8A-8B  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 methods  600 ,  700 ,  900 ,  1000 , and  1100  (e.g.,  FIGS. 6A-6E ,  7 A- 7 B  9 A- 9 B,  10 , and  11 A- 11 B, respectively) are also applicable in an analogous manner to method  800  described above with respect to  FIGS. 8A-8B . For example, the electronic document, insertion point and various magnification levels described above with reference to method  800  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  600 ,  700 ,  900 ,  1000 , and  1100 . For brevity, these details are not repeated here. 
       FIGS. 9A-9B  are flow diagrams illustrating a method  900  of navigating and editing an electronic document in accordance with some embodiments. The method  900  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1 ) with a display and, typically, a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method  900  may be combined and/or the order of some operations may be changed. 
     As described below, the method  900  provides an intuitive way to automatically zooming out at the completion of a text selection gesture to see the entire portion of text that has been selected. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays a portion of an electronic document on the display ( 902 ). For example, in  FIG. 5O , a portion of document  558  is displayed. 
     In some embodiments, the electronic document has a predefined page layout and the predefined page layout is maintained while adjusting display of the document ( 904 ). For example, document  558  has a predefined layout. 
     The device detects a content selection input ( 906 ). For example, gesture  566  dragging selection handle  564 -B is detected ( FIG. 5O ). 
     In response to detecting the content selection input ( 908 ), the device identifies a selected portion of the document in accordance with the content selection input ( 910 ), and in accordance with a determination that the selected portion of the document includes content that is outside of a currently displayed portion of the document, the device adjusts display of the document so that the entire selected portion of the document is displayed on the display ( 912 ). For example, in response to the detection of gesture  566  changing selection range  560  ( FIGS. 5O-5Q ), the portion of document  558  that is selected by selection range  560  is identified. If it is determined that the selected portion (e.g., text  562 ,  FIG. 5Q ) includes content outside a currently displayed portion of document  558 , document  558  is displayed at a different magnification level so that the entirety of selected text  562  is displayed, as shown in  FIG. 5R . 
     It should be understood that, as used herein, “outside” means the portion of selected content that extends beyond the currently displayed portion (e.g., at least some of the selected content is not currently displayed). In some embodiments, adjusting the display of the document is performed automatically without user intervention in response to detecting the content selection input or detecting an end of the content selection input. 
     In some embodiments, the electronic device includes a touch-sensitive surface, and the content selection input includes detecting a contact on the touch-sensitive surface, detecting movement of the contact on the touch-sensitive surface, and ceasing to detect the contact on the touch-sensitive surface ( 924 ). For example, display  112  of device  100  is a touch screen. Gesture  566  detected on touch screen  112  includes a contact, movement of the contact, and ceasing of the contact ( FIG. 5O-5Q ). 
     In some embodiments, in response to detecting movement of the contact on the touch-sensitive surface, the device scrolls the document in accordance with the movement of the contact ( 926 ). In other words, when the display is a touchscreen display and the content selection input includes movement of a contact on the touchscreen display, when the contact moves proximate to an edge of the display, the document is scrolled so as to enable the user to select text outside of the portion of the document that was initially displayed when the contact was initially detected on the touchscreen display. 
     In some embodiments, adjusting display of the document is performed in response to ceasing to detect the contact on the touch-sensitive surface ( 928 ). For example, the entire selection range  560  is shown ( FIG. 5R ) when the contact of gesture  566  ceases to be detected. 
     In some embodiments, the content includes text and/or images ( 914 ). 
     In some embodiments, adjusting display of the document includes changing a magnification level for displaying the document ( 916 ). For example, from  FIGS. 5Q-5R , the magnification level of document  558  was changed, going from a non-page-fit magnification level to a fit whole page magnification level. 
     In some embodiments, adjusting display of the document includes scrolling the document ( 918 ). It should be understood that the document could be scrolled horizontally, vertically, or both horizontally and vertically. 
     In some embodiments, the document has a page width, the selected portion of the document includes at least a full line of the document that spans the page width, and adjusting display of the document includes displaying the document at a page width magnification level ( 920 ). In other words, the document is displayed at a magnification level where the width of the document on the display is approximately equal to the width of the display. 
     In some embodiments, prior to detecting the content selection input, the device displays the document at a first magnification level ( 930 ), and in response to detecting the content selection input, displays the document at a second magnification level different from the first magnification level ( 932 ). 
     In some embodiments, prior to detecting the content selection input, the device enters a document-editing mode ( 934 ), and while in the document-editing mode, displays a soft keyboard on the display ( 936 ). For example, in  FIG. 5O , document  558  is displayed in document editing mode, and keyboard  521  is displayed. 
     In some embodiments, prior to detecting the content selection input, the device enters a document-editing mode ( 938 ), and remains in the document-editing mode after adjusting display of the document ( 940 ). 
     In some embodiments, prior to detecting the content selection input, the device receives a document-editing input ( 942 ), in response to the document-editing input, displays a soft keyboard on the display ( 944 ), and in response to detecting the content selection input (e.g., after zooming out to a page width magnification level), ceases to display the soft keyboard ( 946 ). For example, in  FIG. 5O , keyboard  521  is displayed prior to detection of gesture  566 , and in  FIG. 5R  keyboard  521  ceases to be displayed in response to gesture  566 . 
     In some embodiments, in response to detecting the content selection input, the device displays a selection indicator indicating the selected portion of the document and a menu including options for manipulating the selected portion of the document ( 922 ). For example, selection range  560  and selection options menu  569  ( FIG. 5R ) is displayed in response to gesture  566 . 
     In some embodiments, prior to detecting the content selection input, the device displays a preliminary selection indicator with a first plurality of selection adjustment affordances; and after adjusting display of the document, the device displays an updated selection indicator with either one or more of the first plurality of selection adjustment affordances in different locations in the document (e.g., advanced by one or more words) or a second plurality of different selection adjustment affordances. In particular, when the preliminary selection indicator indicates a selection within a paragraph, the first plurality of selection adjustment affordances enable the preliminary selection to be expanded and/or contracted by a first unit of content; and (e.g., character by character, word by word, or line by line). However, when the updated selection indicator indicates a selection including at least one paragraph break character (e.g., a selection that extends between two adjacent paragraphs) the second plurality of selection adjustment affordances enable the selected portion of the document to be expanded and/or contracted by a second unit of content larger than the first unit of content (e.g., paragraph by paragraph, or section by section). 
     It should be understood that the particular order in which the operations in  FIGS. 9A-9B  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 methods  600 ,  700 ,  800 ,  1000 , and  1100  (e.g.,  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  10 , and  11 A- 11 B, respectively) are also applicable in an analogous manner to method  900  described above with respect to  FIGS. 9A-9B . For example, the electronic document, insertion point and various magnification levels described above with reference to method  900  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  600 ,  700 ,  800 ,  1000 , and  1100 . For brevity, these details are not repeated here. 
       FIG. 10  is a flow diagram illustrating a method  1000  of navigating and editing an electronic document 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. 1 ) with a display and, typically, 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  may be combined and/or the order of some operations may be changed. 
     As described below, the method  1000  provides an intuitive way to automatically zoom to display an object at a size that accommodates the object or, when the object contains editable text, automatically zoom to display the editable text within the object at a size that accommodates the text. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays at least a portion of an electronic document at a first magnification level on the display ( 1002 ). For example, in  FIG. 5T , document  570  is displayed at a certain magnification level. 
     The device detects an input indicating a point within an object in the document ( 1004 ). In some embodiments, the point is an insertion point (e.g., a point where the device will insert additional content such as text or other objects) in response to a user request to insert content. In some embodiments, the point is proximate to the object but within a hit region for the document that extends beyond the perimeter of the object. For example, in  FIG. 5T , the location of gesture  582  indicates a point in object  572  in document  570 , and the location of gesture  580  indicates a point in object  576 . 
     In response to detecting the input ( 1006 ), in accordance with a determination that the object includes respective editable text ( 1008 ), the device selects a second magnification level different from the first magnification level ( 1010 ), where the second magnification level is selected so as to display the respective text at a target text display size, and displays the document at the second magnification level ( 1012 ). For example, in response to gesture  582  ( FIG. 5T ), object  572  is displayed at a magnification level such that text  574  in object  572  is displayed at a target text display size ( FIG. 5V ). 
     It should be understood that the target text display size may be either a predefined target text display size or a user-adjusted target text display size, as described above in greater detail with reference to method  700  and  FIGS. 7A-7B . 
     In some embodiments, the second magnification level is selected without reference to (e.g., independently of) a size of the object ( 1014 ). 
     In response to detecting the input ( 1006 ), in accordance with a determination that the object does not include editable text ( 1016 ), the device selects a third magnification level different from the second magnification level ( 1018 ), where the third magnification level is selected so as to display the object at a target object display size, and displays the document at the third magnification level ( 1020 ). For example, in response to gesture  580  ( FIG. 5T ), object  576  is displayed at a best fit magnification level ( FIG. 5U ). 
     In some embodiments, the object display size is a display size where the object is displayed at a predefined size with reference to a displayed area of the document on the display ( 1022 ). In some embodiments, the object display size is a display size where the object is displayed so that it is as large as possible, while still being fully displayed in the display area (e.g., the object is displayed at a “best fit” size). In other embodiments, the object display size is a display size where the object is displayed so that the width of the object is substantially equal to the width of the display area (optionally, with a predefined buffer between a perimeter of the object and the edge of the display). In other embodiments, the object display size is a display size where the object is displayed so that the height of the object is substantially equal to the height of the display area (optionally, with a predefined buffer between a perimeter of the object and the edge of the display). 
     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 methods  600 ,  700 ,  800 ,  900 , and  1100  (e.g.,  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  9 A- 9 B, and  11 A- 11 B, respectively) are also applicable in an analogous manner to method  1000  described above with respect to  FIG. 10 . For example, the electronic document, insertion point and various magnification levels described above with reference to method  1000  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  600 ,  700 ,  800 ,  900 , and  1100 . For brevity, these details are not repeated here. 
       FIGS. 11A-11B  are flow diagrams illustrating a method  1100  of navigating and editing an electronic document in accordance with some embodiments. The method  1100  is performed at an electronic device (e.g., device  300 ,  FIG. 3 , or portable multifunction device  100 ,  FIG. 1 ) with a display and, typically, 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  1100  may be combined and/or the order of some operations may be changed. 
     As described below, the method  1100  provides an intuitive way to automatically switching back and forth from a user-specified magnification level in a document-display mode to a predefined document-editing magnification level in an editing mode. The method reduces the cognitive burden on a user when navigating and editing an electronic document, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to zoom in on content in a document faster and more efficiently conserves power and increases the time between battery charges. 
     The device displays at least a portion of an electronic document at a user-specified magnification level ( 1102 ). In some embodiments, the user-specified magnification level is a magnification level selected by the user from a plurality of possible magnification levels. For example, the device receives requests to adjust (e.g., increase or decrease) the magnification level of the document (e.g., pinch or depinch gestures on a touchscreen display) prior to receiving a request to enter a document-editing mode. For example, in  FIG. 5X , document  584  is displayed at a user-specified magnification level in response to gesture  590  ( FIG. 5W ). 
     While the document is in a document-display mode, the device receives a request to enter a document-editing mode distinct from the document-display mode ( 1104 ). For example, gesture  592  ( FIG. 5X ) is a request to enter a document editing mode. 
     In response to receiving the request to enter the document-editing mode ( 1106 ), the device enters the document-editing mode ( 1108 ), and displays the document at a predefined document-editing magnification level different from the user-specified magnification level ( 1110 ). For example, in  FIG. 5Y , in response to gesture  592 , document  584  is displayed in document editing mode and at a particular magnification level for editing of a cell (e.g., cell  594 ) in worksheet  591 . 
     In some embodiments, both entering the document-editing mode and displaying the document at the predefined document-editing magnification level are performed in response to receiving the request automatically, without further user input. Enabling a user to both enter the document-editing mode and zoom the document to a magnification level that is comfortable for editing by performing a single gesture reduces the number of steps that are performed by the user to begin editing the document, thereby increasing efficiency and ease of use of the device. In some embodiments, after displaying the document at the predefined-document editing magnification level, the device receives requests to adjust (e.g., increase or decrease) the magnification level of the document (e.g., pinch or depinch gestures on a touchscreen display) prior to receiving a request to exit the document-editing mode. In these circumstances the device would zoom from the current user-adjusted document-editing magnification level to the prior user-specified magnification level upon exiting the document-editing mode. 
     While the document is in a document-editing mode, the device receives a request to exit the document-editing mode ( 1112 ). For example, in  FIG. 5Z , gesture  598  on button  597  is a request to exit document editing mode. 
     In response to receiving the request to exit the document-editing mode ( 1114 ), the device exits the document-editing mode ( 1116 ) and displays the document at the user-specified magnification level ( 1118 ). For example, in FIG.  5 AA, in response to gesture  598 , document  584  is displayed at the same user-specified magnification level as in  FIG. 5X . 
     In some embodiments, both the exiting the document-editing mode and displaying the document at the user-specified magnification level are performed in response to receiving the request automatically, without further user input. Enabling a user to both exit the document-editing mode and zoom the document to a magnification level at which the document was previously displayed by performing a single gesture reduces the number of steps that are performed by the user to return to a document-display mode from the document-editing mode, thereby increasing efficiency and ease of use of the device. 
     In some embodiments, in response to receiving the request to enter the document-editing mode, the device determines whether the document-editing magnification level is within a predefined threshold (e.g., 5%, 10%, 20%, 30% or some other reasonable threshold that reduces jitter) of the user-specified magnification level. For example, if the document-editing magnification level is 100%, the user-specified magnification level will be within the predefined threshold if it is a magnification level between 80% and 120%. In accordance with a determination that the document-editing magnification level is not within the predefined threshold, the device enters the document-editing mode and displays the document at a predefined document-editing magnification level different from the user-specified magnification level. In contrast, in accordance with a determination that the document-editing magnification level is within the predefined threshold, the device enters the document-editing mode while maintaining display of the document at the user-specified magnification level. In other words, when the document-editing magnification level is within the predefined threshold, the device does not zoom to a document-editing magnification level that is different from the user-specified magnification level. 
     In some embodiments, the electronic device includes a touch-sensitive surface, and the request to enter the document-editing mode is detected on the touch-sensitive surface ( 1120 ). In some embodiments, the touch-sensitive surface is separate from the display. In some embodiments, the touch-sensitive surface and the display are combined as a touchscreen display. For example, gesture  592  is detected on touch screen  112 . 
     In some embodiments, the request to enter the document-editing mode is a double tap gesture detected on the touch-sensitive surface ( 1122 ). For example, gesture  592  ( FIG. 5X ) is a double tap gesture. 
     In some embodiments, the request to enter the document-editing mode includes an indication of an insertion point in the document and the insertion point is proximate to a respective portion of the document ( 1124 ). In response to receiving the request to enter the document-editing mode, the device scrolls the document to place the respective portion of the document in a central region of a document display area. (e.g., a central region of the display or a central region of a portion of the display that doesn&#39;t include a soft keyboard) ( 1126 ). For example, the location of gesture  592  ( FIG. 5X ) indicates an insertion point in cell  594 . In  FIG. 5Y , cell  594  is approximately centered in the part of touch screen  112  where document  584  is displayed. 
     In some embodiments, the request to enter the document-editing mode includes an indication of an insertion point in the document and the insertion point is proximate to a respective portion of the document ( 1128 ). Entering the document-editing mode includes providing an input interface for editing the respective portion of the document proximate to the insertion point (e.g., a text cursor and keyboard or a form field for entering a value) ( 1130 ). For example, in  FIG. 5Y , while in document editing mode, keypad  595  and edit field  596  are displayed. 
     In some embodiments, in response to receiving the request to enter the document-editing mode, the device inserts a text cursor at the insertion point ( 1132 ). In response to receiving the request to exit the document-editing mode, the device removes the text cursor ( 1134 ). For example, a text cursor may be inserted into cell  594  when entering document-editing mode, and the text cursor is removed from cell  594  when exiting document-editing mode. 
     It should be understood that the particular order in which the operations in  FIGS. 11A-11B  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 methods  600 ,  700 ,  800 ,  900 , and  1000  (e.g.,  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  9 A- 9 B, and  10 , respectively) are also applicable in an analogous manner to method  1100  described above with respect to  FIGS. 11A-11B . For example, the electronic document, insertion point and various magnification levels described above with reference to method  1100  may have one or more of the characteristics of the electronic document, insertion point and various magnification levels described herein with reference to methods  600 ,  700 ,  800 ,  900 , and  1000 . For brevity, these details are not repeated here.

     The processing unit  1606  is configured to: detect an input indicating a point within an object in the document (e.g., with the detecting unit  1608 ); and in response to detecting the input: in accordance with a determination that the object includes respective editable text: select a second magnification level different from the first magnification level, wherein the second magnification level is selected so as to display the respective text at a target text display size (e.g., with the selecting unit  1610 ); and enable display of the document at the second magnification level (e.g., with the display enabling unit  1612 ); and in accordance with a determination that the object does not include editable text: select a third magnification level different from the second magnification level, wherein the third magnification level is selected so as to display the object at a target object display size (e.g., with the selecting unit  1610 ); and enable display of the document at the third magnification level (e.g., with the display enabling unit  1612 ). 
     In some embodiments, the second magnification level is selected without reference to a size of the object. 
     In some embodiments, the object display size is a display size where the object is displayed at a predefined size with reference to a displayed area of the document on the display unit  1602 . 
     In accordance with some embodiments,  FIG. 17  shows a functional block diagram of an electronic device  1700  configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in  FIG. 17  may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein. 
     As shown in  FIG. 17 , an electronic device  1700  includes a display unit  1702  configured to display at least a portion of an electronic document at a user-specified magnification level; and a processing unit  1706  coupled to the display unit  1702 . In some embodiments, the processing unit  1706  includes a receiving unit  1708 , an entering unit  1710 , a display enabling unit  1712 , an exiting unit  1714 , a scrolling unit  1716 , an inserting unit  1718 , and a removing unit  1720 . 
     The processing unit  1706  is configured to: while the document is in a document-display mode, receive a request to enter a document-editing mode distinct from the document-display mode (e.g., with the receiving unit  1708 ); and in response to receiving the request to enter the document-editing mode: enter the document-editing mode (e.g., with the entering unit  1710 ); and enable display of the document at a predefined document-editing magnification level different from the user-specified magnification level (e.g., with the display enabling unit  1712 ); while the document is in a document-editing mode, receive a request to exit the document-editing mode; and in response to receiving the request to exit the document-editing mode: exit the document-editing mode (e.g., with the exiting unit  1714 ); and enable display of the document at the user-specified magnification level (e.g., with the display enabling unit  1712 ). 
     In some embodiments, the electronic device includes a touch-sensitive surface unit, and the request to enter the document-editing mode is detected on the touch-sensitive surface unit. 
     In some embodiments, the request to enter the document-editing mode is a double tap gesture detected on the touch-sensitive surface unit. 
     In some embodiments, the request to enter the document-editing mode includes an indication of an insertion point in the document; the insertion point is proximate to a respective portion of the document; and the processing unit  1706  is configured to, in response to receiving the request to enter the document-editing mode, scroll the document to place the respective portion of the document in a central region of a document display area (e.g., with the scrolling unit  1716 ). 
     In some embodiments, the request to enter the document-editing mode includes an indication of an insertion point in the document; the insertion point is proximate to a respective portion of the document; and entering the document-editing mode includes providing an input interface for editing the respective portion of the document proximate to the insertion point. 
     In some embodiments, the processing unit  1706  is configured to: in response to receiving the request to enter the document-editing mode, insert a text cursor at the insertion point (e.g., with the inserting unit  1718 ); and in response to receiving the request to exit the document-editing mode, remove the text cursor (e.g., with the removing unit  1720 ). 
     The operations in the information processing methods described above may be implemented by running one or more functional modules in information processing apparatus such as general purpose processors or application specific chips. These modules, combinations of these modules, and/or their combination with general hardware (e.g., as described above with respect to  FIGS. 1A and 3 ) are all included within the scope of protection of the invention. 
     The operations described above with reference to  FIGS. 6A-6E ,  7 A- 7 B,  8 A- 8 B,  9 A- 9 B,  10 , and  11 A- 11 B may be implemented by components depicted in  FIGS. 1A-1B . For example, detection operation  608 , selection operation  612 , and displaying operation  614  in  FIGS. 6A-6E  may be implemented by event sorter  170 , event recognizer  180 , and event handler  190 . Event monitor  171  in event sorter  170  detects a contact on touch-sensitive display  112 , and event dispatcher module  174  delivers the event information to application  136 - 1 . A respective event recognizer  180  of application  136 - 1  compares the event information to respective event definitions  186 , and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer  180  activates an event handler  190  associated with the detection of the event or sub-event. Event handler  190  may utilize or call 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 . 
     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 utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
