Abstract

A keyboard is adjustably supported in an ergonomically neutral position relative to a typist's forearm, wrist and fingers nonetheless that the elevation, and attendant magnitude, of a support also provided to the typist's wrist is conveniently independently variably adjustable. The two adjustments increase comfort while reducing fatigue and repetitive motion injury, particularly carpal tunnel syndrome. A planar keyboard support member is variably supported at typically six (6) different angles from 0.degree. to 15.degree. by a support mechanism typically in the shape of a hinged arm engaging a selected channel, or groove. A padded wrist rest, normally hinged to the keyboard support, is independently adjustable to typically four (4) different elevations, preferably by use of an eccentric cam. The wrist rest preferably defines an interior cavity for holding pencils and other objects. A console for holding paper clips and like objects is selectively attachable to the keyboard support member, and is a copyholder for holding paper copy is in turn selectively attachable to the console.
