Abstract
A handheld communication device and method for affecting movement of a highlighting cursor amongst an array of icons on a display screen is described. In an embodiment, the handheld communication device includes a lighted display, a keyboard and an auxiliary user input, e.g. a trackball, located essentially between the display and keyboard. The auxiliary user input is used to move the highlighting cursor from a first icon located on the display screen, to a second icon located on the display screen. In operation, the highlighting cursor is prevented from moving from a first row of icons to a successive second row of icons when a cross-wise directed force is applied to the auxiliary user input and the highlighted cursor has reached a terminal icon of the first row.
