As the question mentions, I want the the key to right of space which has AltGr written on it (the output of xev is however Alt_R) to perform the the same action as backspace. I tried almost every random combination of setxkbmap backspace:ralt i could come up, unfortunately I find the manual not very helpful. If somebody knows how to understand setxkbmap so I can figure stuff out by myself I'd be even more thankful.

PS: I am running i3 on Lubuntu, if it matters.

    It makes sense to run localectl list-x11-keymap-options to see the available options instead of trying "almost every random combination". If you can't find an option that does what you want you'll have to write a new xkb option. – don_crissti May 19 at 19:43
  • the option I'm looking for does in fact not exist. writing ones own xkb option seems rather tedious and overly complicated for a - imho - standard task as button remapping, but whatever. more importantly, the /usr/share/X11/xkb/rules/evdev file mentioned in the answer you linked says in the first line "do not edit this". whom should I trust now? (and is there no easier way?) – protolyse May 20 at 21:20
  • In theory you should do it via user overrides - as you can see that's even more complicated on some DEs and still involves editing system files (if you can make it work, that is)... – don_crissti May 21 at 9:40
