The entire top surface of the mouse is touch sensitive. It has a left and right mouse button, and then you can drag along the top to scroll up-down or left-right. If you use two fingers to scroll left-right, you can use it as a back-forward control for your web browser. It has a very different feel in your hand than the mighty mouse, which we’ve been using so far. It runs on AA batteries, and I’m not sure how long they’ll last. Probably the best bet would be to use rechargeable NiMH batteries to save on money and be kind to the environment.
