ABSTRACT:
Particularly in hand held alphameric keyboard actuated computers, available room dictates a need to limit the number of keys without sacrificing computer performance. Further, for portable computers reference to an instruction manual is not feasible. Thus usefulness critically depends upon integrated operating instructions. Formerly there is neither room or facilities for instructions, nor room on the keyboard for enough keys. Herein, a computer keyboard of a few keys controlled by a computer multi-mode processing system to have a plurality of roles permits a very large number of computer functions to be entered and controlled. Further in combination with these roles, a computer organized temporary display panel displays keystroke selection indicia for the different keyboard operating roles. This expands instructional notation otherwise possible on the keys and adjacent keyboard locations. Thus, an entire set of alphabetic characters may be entered and processed in the computer by means of as few as six keys in an alpha mode operating the keys in a two stroke per character entry mode. Accordingly, the display panel is programmed by the computer to show with instructional indicia, typically a multiple-choice menu, the role for at least a subcombination of the keys in the current operating role of the keys in effect at the time. This permits detailed keystroke instructions to be available for performing hundreds of operations for which modern computers are capable.
