Mapping left Ctrl + right Ctrl to switch-windows

Question

I'd like to add left Ctrl+right Ctrl to the switch-windows keybinding. Is there a way to distinguish between the left Ctrl and right Ctrl keys when typing that command? Maybe something like:

gsettings set org.gnome.desktop.wm.keybindings switch-windows "['<Alt>Tab','<LControl><RControl>']"

However, that command doesn't work. I was wondering if there are actually key names specifically for the left Ctrl and the right Ctrl keys.

If you're curious why I'd want to do this, I have a Kinesis keyboard, and its default layout makes one stretch their left hand to hit Alt+Tab.

• Edit /usr/share/X11/xkb/symbols/pc

  sudo gedit /usr/share/X11/xkb/symbols/pc
  

• Remove Control_R from Control binding.Put // to comment original line and make new one with Control_L only:

  //modifier_map Control{ Control_L, Control_R };
  modifier_map Control{ Control_L };
  

• Then use System Settings → Keyboard → Shortcuts → Navigation to set it.
