Alternatively referred to as a glide pad, glide point, pressure sensitive tablet, or trackpad, a touchpad is an input device on laptops and some keyboards to move a cursor with your finger. It can be used in place of an external mouse.
A touchpad is operated by using your finger and dragging it across the flat surface of the touchpad. As you move your finger on the surface, the mouse cursor moves in that same direction. Like most computer mice, the touchpad also has two buttons below the touch surface that allows you to left-click or right-click.
