KEYBOARD CONTROLLED AND ACTIVATED POINTING DEVICE FOR USE WITH A WINDOWING SYSTEM DISPLAY

摘要

The present invention provides for a keyboard controlled and activated windowing system pointing device that is typically implemented on a portable data terminal. The pointing device will typically be activated and deactivated by engaging an activation key on the portable data terminal. This allows for multifunctional keys to exist on the keyboard and for the cursor (i.e. the pointer) to be displayed and removed from the display upon activation. Additionally, the pointing device provides for scrolling of the foreground windowed application when the cursor encounters an edge of display. This allows users to access data in oversized windowed applications that do not fit the size limitations of portable data processing displays.
