Abstract
Abstract A computer keyboard mouse system wherein a mouse assembly is integrated into a front or side wall of a keyboard of the computer. A control ball of the mouse assembly protrudes from the front or side wall for control by the operator. To protect against forces directed against the ball of the mouse assembly which could damage it, a ball retaining member is spring loaded such that excessive forces to be protected against will cause the ball to be pushed into the front or side wall. Mouse control keys may be provided adjacent to the mouse assembly on the front or side wall. Also, the control keys can be one or more designated keys of the keyboard itself.
