Touchpad Basics
The following teaches you how to use the touchpad:
qMove your finger across the touchpad (2) to move the cursor. 
qPress the left (1) and right (4) buttons located beneath the touchpad to perform selection and 
execution functions. These two buttons are similar to the left and right buttons on a mouse. 
Tapping on the touchpad is the same as clicking the left button.
qThe center (3) button to mimics your cursor pressing on the right scroll bar of Windows 
applications.
NOTE: When using the touchpad, keep it - and your fingers - dry and clean. The touchpad is sensitive to finger 
movements; hence, the lighter the touch, the better the response. Tapping too hard will not increase the 
touchpad’s responsiveness.
