I have a laptop and an external USB numpad. I'd like to lay the numpad at my left hand and use it for shortcuts, eg. switching desktops, running apps.
I figured that I've got to make Linux treat that keyboard as seperate from the main, by keeping another keymap (eg. when I press 1 on numpad it sends some exotic, nowhere used key).
Long story short : I just want to switch external USB numpad's keymap to keymap that sends weird, nowhere used keys. I know how to map them later.
How can I do it?
