Apparatus for supporting a computer pointing device such as a mechanical or optical mouse or a track ball unit within the footprint of a keyboard. The apparatus supports the pointing device over the keys of a computer keyboard to permit full use of both the pointing device and the keys. The apparatus comprises a platform positionable over at least a portion of the keyboard to support the pointing device and regions formed in the platform to permit manipulation of the keyboard keys through the platform. The regions can be openings through the platform to allow a user's fingers to press the keys directly. The regions can be deformable to permit a user to manipulate the keys underneath the platform indirectly. Alternatively, the keyboard itself can be designed with keys having specially shaped surfaces to support a pointing device. |
