What would you like to do?
On German keyboards, typing the brackets and braces like {[]} is quite annyoing (especialy when programming) so I remapped them to AltGr+asdf which is much better imo. This is tested on Fedora Linux but it should work on most Linuxes.

partial alphanumeric_keys
xkb_symbols "asdfbrackets" {
name[Group1]="brackets on AltGr+asdf";
key <AC01> { [ a, A, braceleft, AE ] };
key <AC02> { [ s, S, bracketleft, U1E9E ] };
key <AC03> { [ d, D, bracketright, ETH ] };
key <AC04> { [ f, F, braceright, ordfeminine ] };
};
# Usage:
# Run as user:
# setxkbmap -v
# Append +asdfbrackets to symbols, for example:
# setxkbmap -v -symbols 'pc+de+us:2+inet(evdev)+asdfbrackets'
# For simplicity and because I am starting bash by default, I just added this to my .bashrc:
# setxkbmap -v -symbols 'pc+de+us:2+inet(evdev)+asdfbrackets' > /dev/null
# However, there is a better solution given in the linke above.

Update - Nowadays I use this as follows:

  • go to /usr/share/X11/xkb/symbols/
  • sudo git init, add, commit (so you keep track of what you are changing and are able to roll back / cherry-pick in case an updated overwrites your changes)
  • Add the four lines directly to the layout you are using. For me this is the file de at the end of section xkb_symbols "nodeadkeys". For programmers I'd recommend the nodeadkeys-layout combined with a compose key, if you need anything like á just type: Compose (e.g. Scroll Lock), ´, a. The ``` as commonly used in markdown becomes much quicker to type. And this enables you to type stuff like ë or ♯♪ as well.
