Abstract: A shelf that fits over the keypad portion of a computer keyboard and extends to the right, providing a convenient work area, closer to the QWERTY keys, for a mouse or other input device. Projections from the underside of the shelf straddle the keypad to position and steady the shelf, while preventing the shelf from touching the keys. Since the shelf is not attached to the keyboard in any way, it can be easily lifted and removed when the keypad is to be used. In one embodiment in which the shelf is about 9 inches by 9 inches, the approximate size of a mouse pad, adjustable legs extend beneath the right end of the shelf to the desk or platform on which the keyboard is resting. These legs provide stability for the shelf. The second embodiment is for use only with an input device requiring a smaller work area, such as a track ball or touch pad.
