    TouchPad Basics
    The following items show you how to use the TouchPad:
    • Move your finger across the touchpad (1) to move the cursor.
    • Press the left (2) 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.
    • Use Acer Bio-Protection fingerprint reader (3) supporting Acer FingerNav 4-way control function 
    (only for certain models) or the 4-way scroll (3) button (only for certain models) to scroll up or down 
    and move left or right a page. This fingerprint reader or button 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 movement; hence, the lighter the touch, the better the response. Tapping too hard will not 
    increase the TouchPad’s responsiveness.
