[Linux-disciples] 2 keymapping questions

[Karl Sokol]

I have a USB numeric keypad for my laptop.  However, the numbers only 
work if I have the NumLK on.  This is annoying because then I cannot use 
UIOPJKL: or M on the laptop keyboard.  Is there a workaround for this so 
I can use both my keyboard and the USB keypad?

Secondly, how can I change the value of keys.  Specifically, I want to 
use my [home] key as another [backspace].
