I can be short about this, I'm used to that
Ctrl-z clears my previous action, for example when typing. Now running Debian 8 With GNOME 3 it does not work, when I press
Ctrl-z the "Enter a command" dialog is shown.What is the debian/GNOME3 equivalent for
Ctr-z (undo) or even better how can I make
Ctrl-z do the Undo'ing?
