The combimouse right unit is a mobile combination keyboard and mouse that can be moved around on a support surface like a conventional mouse. The keys are arranged in the fashion of the right hand side of a conventional QWERTY keyboard.
By default the right unit operates in keyboard mode. When the user grips the right unit and so touches the side of the unit in the area labeled above as 'Contact switch', the right unit automatically changes to mouse mode.
When in this mode, movement of the right unit enables cursor movement on the screen and the keys I, O, J, K, L and < become mouse click buttons.
