1. A portable communication device comprising:
- a housing;
a display disposed within the housing; and
at least one touch input device disposed within the housing, the touch input device being operatively coupled to touch input device control circuitry, wherein the touch input device control circuitry is configured to;
detect a key press in a first key press area of the touch key input device;
detect a key release in the first key press area;
detect a key press in a second key press area adjacent to the first key press area; and
transmit a scroll command if the key press in the second key press area is detected within a predetermined period of time relative to the key release in the first key press area.

Abstract
A portable communication device is equipped with a touch input device configured to provide key press functionality and scrolling functionality. The touch input device is electronically defined to include a plurality of key press areas separated by grey zones. The portable communication device is configured to provide scrolling functionality in response to detection of sequential user contact with multiple key press areas and an intervening grey zone within a predetermined timing trigger.

15. A method of scrolling a display on a portable communication device, the method comprising:
-
detecting contact relative to a touch input device in a first key press area of the touch input device; detecting a release of contact in the first key press area; detecting contact relative to the touch input device in a second key press area adjacent to the first key press area; and scrolling the display in a direction based on the relative position of the first key press area and the second key press area if contact with the second key press area is detected within a predetermined time relative to detecting release in the first key press area. - View Dependent Claims (16, 17, 18, 19)
