Comment 10 for bug 739068

Ctrl-TAB has been suggested above - however, this is already used to cycle through tabs of a particular window of an open application. For an application (which, in general, will have multiple tabs per window) wouldn't a new keyboard shortcut be required ?

I agree that there is a usability issue at present regarding this, as it seems that only effective way to switch is via expo at present (which can be tedious).
