ABSTRACT:
The subject terminal includes a keyboard (20) having a plurality of keys (30-1 through 30-10), each key adapted to accommodate a respective finger of the typist, and apparatus (100, 150) responsive to the depression of one of the keys for generating and displaying a symbol upon a cathode ray tube. Also displayed on the cathode ray tube is a replica (300, 701) of the keyboard and a plurality of symbols (310-1, 510-1, 610-1, et seq) representing different functions for each of the plurality of keys. By altering (702, 703, 704, 705, 706) the label in a key location on the replica, the function associated with that key, for example, the symbol displayed responsive to its depression, may be altered. Thereby the operator need not reposition his fingers among the keys.
