With the press of a button, the scroll wheel will go from regular clicking to smooth free-spinning so that scrolling through long documents or webpages is a breeze.

With the setup utility, the 11 buttons can be mapped to any key sequence. With 3 possible on-board profiles, and even more profiles stored on the computer, you can use a different setup for every program.

If you want to change the weight or balance of the mouse, it comes with several that you can insert in the bottom of the mouse.
