A Touchpad allows you to scroll, select and click without ever plugging in a mouse.
Slide one finger along the center of the Touchpad to move the cursor.
Tap gently to select or press the left button beneath the Touchpad. Tap twice quickly to produce a double-click.
To get right click options, press the button on the right of the Touchpad.
To drag, hold down the left-click button with one finger while dragging the touchpad with another.
