Also called a glide pad, glide point, pressure-sensitive tablet, or trackpad, a touchpad is an input device on laptops and some keyboards. It allows the user to move a cursor with their finger. It can be used in place of an external mouse.
How to use a touchpad
A touchpad is operated 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 lets you left-click or right-click.
Not all laptop touchpads have visible buttons, as shown in the picture. However, the entire touchpad or the bottom section of the touchpad acts as a button when pressing down on the touchpad. Also, tapping the touchpad usually acts as a click.
How to scroll using the touchpad
Scrolling with a touchpad can be done using one of the following methods.
- Place the mouse cursor on the vertical scroll bar on the right side of the program window, then press the left touchpad button. While continuing to press the left button, drag your finger downward on the touchpad to move the scrollbar down.
- Most touchpads allow the user to place two fingers on the touchpad and drag them up or down to scroll.
- Some touchpads have a vertical scroll area built-in on the left or right side. Moving your finger up and down in this section of the touchpad lets you scroll.
