How can I map additional shortcuts to an action, without losing the existing shortcuts for that action?
I have some computers running GNOME version 3 with multiple keyboards (e.g. a notebook computer which is sometimes used with an external keyboard).
These keyboards provide different keys (e.g. some notebook computers don't have the separate cursor movement keys, instead providing only a number pad with these functions) and the keys available for shortcuts are therefore different on the same computer.
So for some commands (e.g.
Switch to Previous Tab) I need to configure an additional keyboard shortcut (e.g. Ctrl + Number pad Page Up) without replacing the existing shortcut for that function.
I need a way to add a shortcut without replacing existing ones. How can I do that?
