I already know I can go to
Code:
 /usr/share/X11/xkb/symbols
for remapping keyboard.
How can I create CTRL+key combinations.... for example CTRL+n = Ů

I would prefer if there is a way staying inside the layout file so if I reinstall the OS I don't need to modify multiples system files, but if there is
no way to do that inside the layout file... it's ok


thanks
