I'm trying to migrate from Mate into Cinnamon. In Mate, it was possible to assign custom modifiers to Switch to workspace on the left of the current workspace. In Cinnamon keyboard configuration applet, the "Mod3" modifier is ignored.
Is there any "backdoor" or command-line way for assigning keyboard assignments for switching workspaces that bypass the configuration applet?
Unfortunately I can't find these shortcuts with dconf-tool nor with gconf-editor.
There is also similar question on AskUbuntu: How to change key bindings for switching workspaces in gnome3?
