Abstract:
1. A method for changing a scroll mode in a computer system for scrolling a document, the method comprising the steps of: placing the computer in a manual scrolling mode; while in the manual scrolling mode, sensing a gesture at a first location made by a pointer on a touch-sensitive surface, wherein the touch-sensitive surface further includes first and second end portions and a scrolling region disposed between the first and second end portions, and wherein the gesture is made on the scrolling region; determining whether the gesture is a touch-and-hold gesture such that the pointer remains substantially still relative to the touch-sensitive surface; responsive to the gesture being the touch-and-hold gesture, placing the computer in an auto-scrolling mode; and receiving, in the auto-scrolling mode, a subsequent sliding of the pointer on the touch-sensitive surface from the first location to a second location without removal of the pointer prior to the subsequent sliding, and in response causing automatic scrolling of the document, wherein the automatic scrolling is performed at a rate that depends upon a difference between the first and second locations.
