Special keys Lock keys The keyboard has three lock keys which you can toggle on and off. Embedded numeric keypad 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 @is on, all alphabetic characters typed are in uppercase. Num Lock (Fn-F11) ] When ] 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.
