I installed synapse on my Cinnamon desktop, and everything worked with the keyboard shortcut Ctrl+Space. Then, at some point, it stopped working properly, and I had to hold down Control and hit space twice. Now it isn't working at all. Control-space seems to make the current window go out of focus, but I can't find it in the cinnamon control center.
I would like to know how to disable it for use with synapse or kupfer, as I don't need this cinnamon Control-space anyway. I run cinnamon 2.0.10, in case it helps.
gnome-control-center
instead. While cinnamon 2 is supposed to be free of Gnome there might be some residual settings still affected. I don't have version 2 installed yet so I can't check but have you looked through all the keyboard shortcuts in the "Windows" and "Universal Access" sections?gnome-do
(which is equivalent to synapse) if that works for you, see here for a tip on how to make it work without needing to hit space twice.
