Abstract
Abstract A keyboard positioning system in which the keyboard is positioned with its rear edge substantially lower than its forward, or operator edge in order that the operator might use the keyboard with the plane of the operator's hands parallel to, or below the line of the operator's forearm, thus reducing the incidence of carpal tunnel syndrome. A hand support bar is provided to support the operator's hands while keyboarding.
