(1) Issue/Bug Description/Video Capture/Screenshots

When you set keyboard shortcut, it resets if key is invalid.

I try to use my ":" key as part of window-focus-right shortcut.

I set value as <Super>: which should be valid, but it resets back to <Super>l default. same for quotes key.

(2) Steps to reproduce

1. Go to settings
2. Keyboard
3. Window shortcuts
4. Set window-focus-right to <Super>:
5. Quit settings
6. Open same settings to check if it has been reset

Try <Super>colon

Works!

Maybe there should be reference to all the shortcuts we could use in that settings page. Currently just Super, Shift and Primary are listed
