Claims8
A method of activating and using a scrolling function for a list that is displayed on a display screen, said method comprising the steps of:
- (1) detecting touchdown of a first pointing object on a touchpad within a scroll zone to thereby activate a scrolling function;
- (2) detecting a second pointing object on the touchpad and not within the scroll zone while the first pointing object is still in contact with the touchpad in the scroll zone;
- and
- (3) dragging the second pointing object to thereby cause scrolling within a list on a display screen.
A method of activating and using a scrolling function for a list that is displayed on a display screen, said method comprising the steps of:
- (1) detecting touchdown of a first pointing object on a touchpad within a scroll zone to thereby activate a scrolling function;
- (2) detecting a second pointing object on the touchpad and not within the scroll zone while the first pointing object is still in contact with the touchpad in the scroll zone;
- and
- (3) determining if the second pointing object is above or below a vertical center line of the touchpad;
- and
- (4) scrolling up within a list shown on a display screen when the second pointing object is disposed above the vertical center line of the touchpad, and scrolling down within the list shown in the display screen when the second pointing object is disposed below the vertical center line of the touchpad.
A method of activating and using a scrolling function for a list that is displayed on a display screen, said method comprising the steps of:
- (1) detecting touchdown of a first pointing object on a touchpad outside a scroll zone;
- (2) detecting touchdown of a second pointing object on the touchpad within the scroll zone while the first pointing object is still in contact with the touchpad;
- and
- (3) dragging the second pointing object within the scroll zone to thereby cause scrolling within a list on a display screen.
