Ubuntu – How to map a key to work like mouse button including its modifiers

If you first remove the lock modifier from the Caps Lock key you should then be able to assign the key in Keyboard Shortcuts, use the command below to do that:

echo  'remove lock = Caps_Lock' | xmodmap -

You should be able to simply use Keyboard Layout >> Options >> Ctrl key position >> Right Alt as Right Ctrl, but this doesn't work. This has already been filed against Debian as Bug#663218

1. Start fresh by deleting ~/.Xmodmap.

2. Note that you do not need to clear Control and Mod1. This makes it easier to change only what you want. Your ~/.Xmodmap shoud be:

   !Swap right control and right alt
   remove Control = Control_R
   remove Mod1 = Alt_R
   keycode 105 = Alt_R
   keycode 108 = Control_R
   add Control = Control_R
   add Mod1 = Alt_R
