Numeric keypad
With the Num Lock key you can manually switch on or off
the numeric keypad on your keyboard. Also, computers' BIOS settings often
include an option to decide if the computer should be started with the
numeric keypad enabled. Otherwise, this is a way to configure it:
-
Install the numlockx package.
-
Open Startup Applications
and add a startup program with the command: numlockx on
The second step may be redundant on your computer, so try without it first.
