Abstract
A computer system employs a keyboard that includes an integrated pointing device coupled to a pointing key. The system has a typing mode of operation and a pointing mode of operation. In the pointing mode, the pointing key is used to enter pointing information, thereby obviating a discrete pointing device such as a mouse. The system may be switched between the typing mode and the pointing mode explicitly by predetermined commands. Alternatively, the system may be switched into the pointing mode implicitly by monitoring and timing keyboard events following a pointing key press.
