<p>A selective call radio (10), including a housing (12), has a display (18) and touchpad (22) of the same size. The display is mounted to a surface on one side of the housing, and the touchpad is mounted to another surface on an opposite side of the housing, directly opposite the display. A screen surface of the display and a touch surface of the touchpad are parallel and have a same number of edges. Sliding of a user's fingertip on the touchpad in a right-to-left direction causes movement of a pointer (26) in a left-to-right direction, and vice versa. Movement on the touchpad causes movement in an identical amount on the display.</p> |
