Using the Keyboard
The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and
twelve function keys, and two 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 Key
Description
Caps Lock
When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock
<Fn> + <F11>
When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a
calculator (complete with the arithmetic ope, -, *, 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
<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.
