A computer touchpad lets you move the pointer across the screen without the mouse. Not every touchpad works in the exact same manner, but as a general rule when you slide your finger across the pad, the pointer moves with it. The touchpad also lets you scroll, double-click and drag items.
Two Finger Exercise
If you have scrolling enabled on your touchpad, it's simple: slide two fingertips across the pad rather than one. Some systems allow one-finger scrolling. You can enable the touchpad in your control panel or system settings. The settings also let you control how fast the scrolling works.
