ABSTRACT:
A keyboard has a plurality of key operated switches, each including a key having a manually engagable key surface. The keyboard selectively determines the function produced by operation of the key operated switches, and displays on each key its current function. The display provides a sensible output indication corresponding to the current function of each key, and includes an elongate strip symbol bearing member located alongside each key and lying in a plane generally perpendicular to the plane of each key surface.
