ABSTRACT:
A keyboard for use with typewriters, computers, work processors or the like has two components, one operated by each hand. One of the components includes a small array of keys used for typing in characters. The other component has a number of keys for re-mapping the character input keys. Each of the mapping keys assigns a different set of characters or functions to the character keys, so that all alphabetic, numeric and punctuation characters, computer functions and controls and word processing commands can all be entered using a single small array of keys with minimum finger movement.
