I would like to change the default shortcut to switch back and forth to the tty. By default it is ctrl + alt + F#. I have tried making a custom shortcut using Ubuntu's keyboard settings but it only worked while using the graphical interface when i switch back to tty it doesn't work. So I need to figure out how to change the default binding of the ctrl + alt + F# shortcut to make a single key toggle back and forth between two TTYs.
