Comment 469 for bug 1218322

Dear Ubuntu users and developers!

Recently I have tested RedHat 7 RC, it uses GNOME 3.8 (Gentoo too) in which there are modifiers-only switch to next source - "gnome-control-center keyboard" -> Shortcuts -> Typing -> Modifiers-only switch to next source (here are <Right Shift>, <Left Ctrl>, <Alt+Caps Lock>, <Right Ctrl+Right Shift>, <Ctrl+Shift>, <Caps Lock>, <Right Ctrl>, <Left Shift>, <Shift+Caps Lock>, <Left Ctrl+Left Shift>, <Alt+Shift>, <Left Alt>, <Scroll Lock>, <Alt+Space>, <Left Win>, <Alt+Ctrl>, <Right Win>, <Right Alt>, <Menu>, <Left Alt+Left Shift>).

For better Ubuntu 14.04 user-experience we must support all these shortcuts in all sessions (Unity, GNOME, GNOME FlashBack - Compiz, GNOME FlashBack - Metacity). You can consult with my Google Docs table (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dEJrX2NRYlpLWWVzSWxsVXU4ck9HYVE&usp=sharing) for testing, tracking progress and determine which combinations do not work. The document may be bit outdated but you can update it by yourself.

This bug may be marked as fixed only if all hotkeys work on all sessions.
