Abstract:
A method for scrolling a multi-section document is disclosed, including displaying on a display an electronic document that includes a plurality of document sections separated by respective logical structure boundaries; detecting a gesture on a touch-sensitive surface, the gesture having an initial velocity that exceeds a predefined speed threshold such that the gesture will scroll the electronic document more than one document section; initiating scrolling of the electronic document on the display at the initial velocity in accordance with an initial scrolling speed versus scrolling distance function; while scrolling the electronic document, adjusting the scrolling speed versus scrolling distance function so that when the scrolling speed becomes zero, a first logical structure boundary in the electronic document is displayed at a predefined location on the display; and, scrolling the electronic document in accordance with the adjusted scrolling speed versus scrolling distance function.
