twelve function 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 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 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.
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.
