CTRL-ALT-TAB swaps between all applications in all workspaces and this is the behaviour that I want for ALT-TAB (lets be honest, CTRL-ALT-TAB breaks your fingers!
How do I switch them around in Cinnamon 2 (LM16 Petra)
I found Alt-Tab as "Cycle through open windows"
in "System Settings -> Keyboard -> Keyboard shotcuts [ Categories : Cinnamon ]
" but I can't see "Cycle through ALL open windows
" (or what ever it is really called
I'm not afraid to use gconf-editor or something like that, if that is what it takes to make this important key combination work as I want it to.
