I am using a swiss apple keyboard at the moment. This keyboard requires some unreasonable finger acrobatics to type a backslash (shift+right alt+7). I'd like to bind the backslash to another key combination, specifically shift+4, which right now produces a "ç" which I never need.

I use Linux mint xcfe.

For permanent solution issue command in console:

echo 'keycode 13 = 4 backslash 4 ccedilla onequarter dollar onequarter' >> $HOME/.Xmodmap

then switch layout or issue xmodmap - < $HOME/.Xmodmap

For a one time (or to be executed at each startup from $HOME/.xinitrc): xmodmap -e 'keycode 13 = 4 backslash 4 ccedilla onequarter dollar onequarter'

  • Did you forget to remove the initial 4? Feb 1, 2013 at 2:23
  • Nope, that's needed: otherwise you would get a `` on pressing the 4 key alone. Feb 1, 2013 at 8:37
  • In that case, I don't understand the syntax. xmodmap -e 'keycode 79 = 4 backslash' gives my the digit 4 for the numpad key "7" (= 79; got that from xev), dropping the backslash gives the same result; xmodmap -e 'keycode 79 = backslash' on the other hand gives me a backslash for the same key. This seems straightforward, but apparently not so? Feb 1, 2013 at 20:03
