Portable Electronic Device, Method, and Graphical User Interface for Displaying Electronic Documents and Lists

摘要

In a computer-implemented method, a portion of an electronic document is displayed on a touch screen display of a portable multifunction device. The displayed portion has a vertical position and a horizontal position in the electronic document. An object is detected on or near the displayed portion of the electronic document. In response to detecting the object, a vertical bar and a horizontal bar are displayed on top of the displayed portion. The vertical bar has a vertical position on top of the displayed portion that corresponds to the vertical position in the electronic document of the displayed portion. The horizontal bar has a horizontal position on top of the displayed portion that corresponds to the horizontal position in the electronic document of the displayed portion. After a predetermined condition is met, display of the vertical bar and of the horizontal bar is ceased.
