I tend to "mistype" a lot when, for instance, in emacs or such. And by some unfortunate coincidence, I happen to change quite often the number of workspaces in xubuntu, and I end up reorganizing all windows and stuff again and again. It should be a combination of keys close to a common I use, but I couldn't find it so far.
Which combination of keys change the number of active workspaces in xubuntu?
How do I disable it?
