A sensoris preferably positioned within the housing for sensing lateral movement of the rotatablemember. In response to sensed lateral pivotable movement of the rotatable member,the image is horizontally scrolled, preferably in the direction of the lateral movement.The scrolling speed can be affected relative to the amount of displacement of therotatable member and/or the amount of time that the rotatable member is displaced apredetermined amount.
