i3 variables in Xresources should include a binding for back_and_forth

[StephenHogsten]

The back and forth command can be useful for switching back to the previously focused workspace. It would be convenient for this to be defined with a Xresources variables for users. I would suggest a default of alt+super+tab since it's not currently occupied.

Thanks @StephenHogsten , that's a great idea! Exact line to add to i3 to achieve this:

bindsym $mod+$alt+Tab workspace back_and_forth
