keys, and twelve function keys.
Special keys
Lock keys
The keyboard has three lock keys which you can toggle on and off.
Lock Key Description
Caps Lock When Caps Lock is on, all alphabetic characters are typed in uppercase.
Num lock
(Fn-F11)
When Num Lock is on, the embedded numeric keyboard can be used. The keys

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.

Embedded Keypad
The embedded 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.
To use the embedded numeric keys, toggle the Num Lock on by pressing the Fn + F11 keys simultaneously.
With the embedded keypad turned on, the following actions are possible:
NOTE: If an external keyboard or keypad is connected to the computer, the Num Lock feature automatically
shifts from the internal keyboard to the external keyboard or keypad.
