I have problem, that I can't press 4key shortcut, I'm using workspaces to work, but now I find that I cant move windows to another workspace. Shift+ctrl+alt+KEY doesnt work, it always grab only 3keys(shift+alt+arrow,ctrl+alt+arrow, ...) . I installed Fedora yesterday. Previously I had Ubuntu and it worked.
If I open keyboard layout and press shift+ctrl+alt+arrow, all are highlighted.
Thanks for help.
Gnome3 + all extensions off
