ABSTRACT:
An apparatus has a keyboard panel with a QWERTY array of alphabetic key actuation indicia. The apparatus further has a QWERTY array of keys that are free of alphabetic key actuation indicia, and are located adjacent to corresponding alphabetic key actuation indicia on the keyboard panel. Other parts of the apparatus include an output device responsive to actuation of the keys, and a processing device operatively coupled between the keys and the output device. Summarized alternatively, the apparatus includes a keyboard with keys arranged in arcuate horizontal rows. The keys in each row have centerlines projecting radially from a respective common centerpoint.
