ABSTRACT:
The device is a translucent plastic mask or overlay which fits over the keyboard of the computer input/output station to label the keys with their functions according to the selected mode of operation. A projecting portion along one of the edges of the mask extends into a slot adjacent the keyboard where a series of code segments forms an optical code which is read by a corresponding series of lamp and photocell pairs to provide the computer with the information to cause its mode of operation to correspond with the keyboard legends.
