Comment 284 for bug 1218322

Hello! Thank you for update, William!

I did some tests. I have enabled proposed-updates in my clean Ubuntu 13.10 installation.
So I use latest packages:
gnome-control-center 1:3.6.3-0ubuntu45
gnome-settings-daemon 3.8.5-0ubuntu11.1.

I made tests on clean user profile at each hotkey assign.
I prepared a table in Google Docs (https://docs.google.com/spreadsheet/ccc?key=0Ao5e713Ig9g_dEJrX2NRYlpLWWVzSWxsVXU4ck9HYVE&usp=sharing).

My test results are:
1. The default hotkey - Super+Space and Shift+Super+Space do not work in Unity session, but work in GNOME session flashback (with or without effects). We have separate bug for it (bug 1245136).
2. Alt+Shift works.
3. Ctrl+Shift works, but breaks all shortcuts, which start from Ctrl+Shift+ (for example, copy and paste in gnome-terminal is broken - see bug 1246656). Current behaviour of Ctrl+Shift disallows to select words by Ctrl+Shift+arrows. I unable to enter Firefox private session (because of Ctrl+Shift+P is broken too). So Ctrl+Shift is almost fully broken.
4. Shift+Shift works, but I can't set this shortcut from gnome-control-center in Unity (it tells only Shift R), I set it from GNOME Session FlashBack gnome-control-center (it reports Shift+Shift R).

In GNOME FlashBack (with effects) Alt+Tab is broken (bug 1246643). I don't know is it connected with layout-switching bugs.
Ctrl+Alt+T (launch terminal) still does not work in non-latin layout (it is bug 1226962) in Unity and GNOME Session FlashBack (without effects), but works in GNOME Session FlashBack (with effects) .

So the bug is partially fixed.

The aforementioned Google Docs table may be editable by anyone with link. If you want to test other hotkeys for keyboard layout change or test them under Ubuntu-GNOME - you can do it and add lines to the table.
