Alt-F10 is supposed to be toggle maximise window but it doesn't function.
I've checked it is bound in ccsm > General > Keybindings and it is, but it's just not working. Ditto minimise.
Also the same is confirmed by Settings > Keyboard > Shortcuts
Is there something else controlling/masking/blocking this?
(Nb. There are lots of posts on here about Unity; I am not using Unity, but Gnome Shell)
