    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 (3) 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.
    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.
    FunctionLeft Button (2)Right Button (3)Main TouchPad (1)
    Execute Quickly click twice. Tap twice (at the same speed 
    as double-clicking a mouse 
    button).

    finger on the TouchPad to 
    drag the cursor.Tap twice (at the same speed 
    as double-clicking a mouse

    the TouchPad on the second 
    tap and drag the cursor.

    Using the Keyboard
    This computer has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock, 
    function 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.
    Lock keyDescription
    Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
    Num Lock 
     + When Num Lock is on, the embedded keypad is in numeric mode. 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.
    Scroll Lock  + 
    When Scroll Lock is on, the screen moves one line up or down when you press 
    the up or down arrow keys respectively. Scroll Lock does not work with some 
    applications.
