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.

When ] 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.

When [ is on, the screen moves one line up or down when you press the up

or down arrow keys respectively.

[ does not work with some applications.
