Using the Keyboard The keyboard has full-sized keys and an embedded keypad, separate cursor keys, one Windows key and twelve function keys. Lock Keys and embedded numeric keypad The keyboard has three lock keys which you can toggle on and off. Lock Key Caps Lock Num lock + Scroll lock + Description When Caps Lock is on, all alphabetic characters typed are in uppercase. 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. 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. 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.
