Intuos4 Mouse...The five-button Intuos4 Mouse scroll mouse is an alternative to the pen, for those who might prefer mouse input for certain tasks. The Intuos4 mouse uses the same cordless and battery-free technology as the pen working smoothly on the surface of the tablet. The mouse includes an integrated middle button, a rolling finger wheel, and two additional buttons that can be used for quickly scrolling up and down. The buttons can be customized for a variety of functions and actions in the Wacom Control Panel. Note: The Intuos4 Mouse works with Intuos4 generation tablets only.
