Comment 3 for bug 947613

Better logic would be welcome too. Speaking for 3D UI aswell.
Pressing alt in fullscreen provokes HUD and alt action in program in question, resulting lose of focus from program.
Realy annoying.

If I disable HUD key from CCSM it disables alt+tab too. That ain't so good either.

For fullscreens, I think one option would be that super button, that would bring launcher & dash from back to front and then taping alt would bring HUD in focus.
Other option would be that none of unity keys would not work, except ctrl+alt+{left,right,up,down} to change workspace. On other workspace fullscreen focus would not be problem anymore.
