You have no idea how much you just made my day!
I was messing around with Xmodmap, and it even worked… for a while, until it started loading excessively slowly and turning off every once in a while.
I figured I could maybe try to remap some more of my keys and, preferably, do it permanently (and without he pesky Xmodmap), and at that point, I found your very detailed and well-explained article. I’m happy that I know how to use Xmodmap when needed, but the trouble I had to go through to understand how to remap my goddamn Caps Lock… this is heaven compared to that!
Thank you so much, I’m off to remap my keyboard :)
