In a computer-implemented method, a portion of an electronic document is displayed on the touch screen display. The displayed portion of the electronic document has a vertical 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 on or near the displayed portion of the electronic document, a vertical bar is displayed on top of the displayed portion of the electronic document. The vertical bar has a vertical position on top of the displayed portion of the electronic document
that corresponds to the vertical position in the electronic document of the displayed portion of the electronic document. After a predetermined condition is met, display of the vertical bar is ceased. The vertical bar is displayed for a predetermined time period when the portion of the electronic document is initially displayed.
