Touchpad

The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimum comfort and support.

Touchpad Basics

The following items teach you how to use the touchpad:

!Move your finger across the touchpad to move the cursor.

!Press the left and right buttons located on the edge of the touchpad to do selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad produces similar results.

Function	Left Button	Right Button	Tap
Execute	Click twice		Tap twice (at the same
	quickly		speed as double-clicking
			the mouse button)
Select	Click once		Tap once
Drag	Click and hold,		Tap twice (at the same
	then use finger		speed as double-clicking
	to drag the		a mouse button) then hold
	cursor on the		finger to the touchpad on
	touchpad		the second tap to drag the
			cursor
Access context		Click once
menu

NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping harder will not increase the touchpad’s responsiveness.
