Keyboard support system

A keyboard support system attaches to an edge of a work surface. The work surface includes a working surface and an underside. The keyboard support system includes a keyboard platform configured for supporting a keyboard. A U-shaped mounting bracket includes a top wall having a lower surface, a monolithic bottom wall and a middle wall interconnecting the top wall and the bottom wall. The bottom wall has an upper surface and a lower surface with a pair of integral, opposing guide rails projecting therefrom. Each guide rail has a length oriented substantially parallel to the bottom wall. The middle wall is configured to both resiliently bias the lower surface of the top wall against the working surface of the work surface and resiliently bias the upper surface of the bottom wall against the underside of the work surface, thereby clamping the work surface between the top wall and the bottom wall. A sliding device is retained between the guide rails of the bottom wall and is slidably positioned along the lengths of the guide rails. A mounting arm interconnects the keyboard platform and the sliding device.
