Using the Keyboard

The computer has a close-to-full-sized keyboard and an embedded numeric keypad, separate
cursor, lock, function and special keys.

Lock Keys
The keyboard has three lock keys which can be toggled on and off.
Lock key
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock When Num Lock is on, the embedded keypad is in numeric mode. The keys
<Fn> + <F11> function as a calculator (complete with the arithmetic operators +, -, *, and /).
Use this mode when doing a lot of numeric data entry. A better solution would
be to connect an external keypad.
Scroll Lock When Scroll Lock is on, the screen moves one line up or down when the up or
<Fn> + <F12> down arrow keys are pressed respectively. Scroll Lock does not work with
some applications.
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 key caps. To simplify the keyboard
legend, cursor-control key symbols are not printed on the keys.
