Abstract: A computer keyboard with palm support surfaces, and controls providing mouse functions, added to each side of the keyboard. The palm support surfaces are downward sloping, and/or downward curved convex surfaces, on either side of the keyboard, descending from peaks near each top rear corner of the keyboard, laterally away from the keyboard, and towards the front of the keyboard. Outside edges of the palm support surfaces may narrow and curve inward toward the front of the keyboard to allow a more natural hand position. The controls include selection buttons, normally located on a mouse, to the left of the keyboard, and a positioning device normally located on a mouse, to the right of the keyboard, and are generally embedded to the rear of each palm support surface. The controls and palm support surfaces allow a more natural hand placement and avoid pressure on the carpal tunnel area.
