ABSTRACT:
A method and apparatus are disclosed for controlling an electronic display using a keyboard to allow designation of desired regions on the display or in the memory of the system. A method of designating desired regions on the display under control of a keyboard which has at least one designation key includes the steps of positioning a cursor at a first location in fixed relationship to the desired region, activating a first designation key, and supplying through the keyboard signals to indicate a second location in fixed relationship to the selected region to cause a portion of the selected region between the first location and the desired location to be designated. The apparatus for designating a region on a display includes a processing unit coupled to the display, a keyboard connected to the processing unit to control the display, and first and second designation keys coupled to the processing unit for causing the processing unit to search the display for a pattern entered into the keyboard while at least one of the first or second keys is activated.
