I have a ubuntu 16.04 LTS.
My Num Lock was ON, and I accidentally pressed a key on numberpad.
And I noticed that the keys change functionality, like,
8 - up arrow 4 - left arrow 6 - right arrow 2 - down arrow
When I press 3 on number pad, it types ~(tilde character)
This behaviour is only on the command-line, and not on any text-editor.
I want to turn these keys completely off. How to do that?
I was having windows earlier, windows was not having this behaviour. So, its not hardware related I think.
