An adjustable keyboard for typewriters, computers, and similar machines, is divided laterally into first and second sets of keys, with each set being adjustable about each of two mutually angulated axes so as to change the planes of the sets relative to each other and relative to the support, and also to allow each set to be angularly shifted in its own plane. The keys of each set are mounted for individual adjustment angularly, laterally, and in height. This allows the overall configuration of each set of keys to be individually adjusted for the convenience, physical, and operating characteristics of the arms, hands, and fingers of each operator.
