Comment 3 for bug 923384

I also run into this issue (HUD showing when trying to switch keyboard layouts with alt+shift) and tried as a countermeasure to change the HUD enabling key combination using ccsm.
Sadly none of the key bindings i tried (alt+space, ctrl+space, ctrl+shift+space, Lshift+Rshift, ctrl+alt+space, alt+Home, ctrl+Home, Fn+alt, fn+altgr, ctrl+ctrl are some of my tries) succeeded at that purpose. HUD is only enabled using the default (alt) enabling key.
As you can understand, this is making writing bilingual texts (something i have to do very often) very difficult, so i am forced to totally disable this otherwise very nice feature of Unity.
Please reconsider the priority of this bug, or otherwise please advise me on where (i mean which application) to file a bug report about not having the ability to change the HUD mapping.
