Ubuntu - German Characters on English Keyboard

I have two keyboards - USA and UK. I prefer those over German keyboard due to brackets location. The idea is to access German characters with following key combinations:

• Right ALT + s -> ß
• Right ALT + a -> ä
• Right ALT + o -> ö
• Right ALT + u -> ü

This can be achieved with xmodmap. Just create in your home directory file called .Xmodmap and copy content below into it.


For USA keyboard:

keycode 108 = ISO_Level3_Shift ISO_Next_Group ISO_Level3_Shift ISO_Nexkt_Group
keycode  30 = u U u U udiaeresis Udiaeresis
keycode  32 = o O o O odiaeresis Odiaeresis
keycode  38 = a A a A adiaeresis Adiaeresis
keycode  39 = s S s S ssharp

For UK keyboard:

keycode 108 =  Mode_switch Mode_switch Mode_switch
keycode  30 = udiaeresis Udiaeresis u U udiaeresis Udiaeresis
keycode  32 = odiaeresis Odiaeresis o O odiaeresis Odiaeresis
keycode  38 = adiaeresis Adiaeresis a A adiaeresis Adiaeresis
keycode  39 = ssharp ssharp s S s S ssharp

You can also manually load key bindings by executing xmodmap .Xmodmap
