Num Lock <Fn>+<F11>

When Num Lock is on, the embedded keypad is in numeric mode. The marked keys function as a numeric keypad (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. An alternative solution may be to connect an external keypad.

Scroll Lock <Fn>+<F12>

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.
