I’m on Ubuntu 12.10 and I’ve seen that I can use
sudo dpkg-reconfigure keyboard-configuration
to control which key triggers the dead key behaviour on my keyboard (which normally resides on AltGr). I would like to use both Alt as well as AltGr to type dead keys.
However, when I select “Both Alt Keys“ in the “Key to function as AltGr” step, the alt-tab application switcher shortcut stops working, presumably because the key combo is swallowed by whatever controls text input. Is there any way to make both work, since there is no dead key on tab?
