    Touchpad Basics (with fingerprint reader)
    The following items show you how to use the touchpad with Acer Bio-Protection fingerprint reader:
    •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.

    and special keys.
    Lock Keys and embedded numeric keypad
    The keyboard has three lock keys which you can toggle on and off.
    The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters 
    located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols 
    are not printed on the keys.

    function as a calculator (complete with the arithmetic operators +, -, *, and /). Use 
    this mode when you need to do a lot of numeric data entry. A better solution 
    would be to connect an external keypad.

    the up or down arrow keys respectively. Scroll Lock does not work with some 
    applications.
