Device, method, and graphical user interface for navigating and annotating an electronic document

An electronic device, comprising:

• a display;
• a touch-sensitive surface;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying a document having a user-specified area annotated by highlighting that includes highlighting of a first type;
• detecting a contact at an initial contact location on the touch-sensitive surface that corresponds to an initial location on the display;
• detecting movement of the contact on the touch-sensitive surface;
• and,
• in response to detecting the movement of the contact on the touch-sensitive surface, in accordance with a determination that the initial location on the display is within the user-specified area annotated by highlighting, adding annotation with highlighting of a second type distinct from the first type to the user-specified area annotated by highlighting in accordance with the movement of the contact.

A graphical user interface on an electronic device with a display, a touch-sensitive surface, a memory, and one or more processors to execute one or more programs stored in the memory, the graphical user interface comprising:

• a document having a user-specified area annotated by highlighting that includes highlighting of a first type;
• wherein:
• a contact is detected at an initial contact location on the touch-sensitive surface that corresponds to an initial location on the display;
• movement of the contact on the touch-sensitive surface is detected;
• and,
• in response to detecting the movement of the contact on the touch-sensitive surface, in accordance with a determination that the initial location on the display is within the user-specified area annotated by highlighting, annotation with highlighting of a second type distinct from the first type is added to the user-specified area annotated by highlighting in accordance with the movement of the contact.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with a display and a touch-sensitive surface, cause the device to:

• display a document having a user-specified area annotated by highlighting that includes highlighting of a first type;
• detect a contact at an initial contact location on the touch-sensitive surface that corresponds to an initial location on the display;
• detect movement of the contact on the touch-sensitive surface;
• and,
• in response to detecting the movement of the contact on the touch-sensitive surface, in accordance with a determination that the initial location on the display is within the user-specified area annotated by highlighting, add annotation with highlighting of a second type distinct from the first type to the user-specified area annotated by highlighting in accordance with the movement of the contact.
