The following teaches you how to use the touchpad:
Move your finger across the touchpad (2) to move the cursor.
Press 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.

numeric mode. The keys function as a calculator |
|
(complete with the arithmetic operators +, -, *, and /). |

When Scroll Lock is on, the screen moves one line up |
<Fn>+<F12> |
or down when you press the up or down arrow keys |
|
respectively. Scroll Lock does not work with some |
|
applications. |
