Abstract

A programmable key for displaying messages to an operator so as to draw the operator's attention actively to the key is presented. The key carries a liquid-crystal display 23 for showing at least one message on the key according to the program chosen, means for creating messages on the liquid-crystal display and means for enabling the liquid-crystal display to be translated from one position to another position. In typical operation, the liquid-crystal display is initially activated to show a message at the key's neutral position. When the key 13 is depressed the liquid-crystal display automatically reactivates to show a second message. At either position, the key may show a blank screen by appropriate energization or de-energization of the liquid- crystal display. <IMAGE>
