Abstract: A device for use with a telephone transceiver to automatically generate any one of N stored dialing codes employs N digital phone number storage registers, and a set of N/2 pushbuttons. A display panel having N display areas on which the stored numbers may be written is supported in sliding relationship with the pushbuttons so that either of two display areas may be moved into operating relationship with each button. Switches controlled by the position of the panel and by the command buttons connect one of the phone number storage registers to a dial signal generator.
