This Control Panel allows you to control the mouse parameters, such as how far it should move in response to a specified physical movement. It also controls double-click speed, and has an option called Pointer Trails. This is a visual device making movement more obvious by adding temporary trials to the pointer as it moves. You can swap mouse buttons over here too so that if you're left handed, you can use a mouse more comfortably. The other tab allows you to change the style of pointer used, so instead of a normal arrow, you can have a little mouse instead. See also Accessibility, Desktop Themes, Intellimouse
