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 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
w
and
y
respectively.
Scroll Lock does not work with some applications.
