How to change one character for another on a keyboard layout in KDE/Ubuntu

Question

I would like to enter @ sign when I type № on my Russian keyboard layout.

I'm using KDE 4.13 on Ubuntu system.

I understand that I need to modify the layout somehow. What is the best way to do it?

Answer 1

I'd probably start by using xev to figure out the keycode sent by your keyboard for №, then use xmodmap to remap that key.
