xmodmap & multiple layouts

Question

I currently use two keyboard layouts with an xorg.conf like

Section "InputClass"
  Identifier      "Keyboard Defaults"
  MatchIsKeyboard "yes"
  Option          "XkbLayout" "us, de"
  Option          "XkbOptions" "grp:caps_toggle"
EndSection

Now I want to map AltGr to use it as the context menu key. This can be done with

xmodmap -e "keycode 108 = Menu"

but only modifies the key on the first layout. How can I modify it on all layouts? Could something be done using advanced XkbOption or XkbLayout parameters?

Answer 1

echo -e "setxkbmap de\nxmodmap ~/.Xmodmap.DE" > ~/key-de && chmod +x ~/key-de
echo -e "setxkbmap us\nxmodmap ~/.Xmodmap.US" > ~/key-us && chmod +x ~/key-us
xmodmap -pke > ~/.Xmodmap.DE
xmodmap -pke > ~/.Xmodmap.US

Now just edit ~/.Xmodmap* as you like and attach shortcuts to scripts ~/key-de and ~/key-us.
