I have a question much like this one: keyboard shortcut to switch to next window
I'm looking for a shortcut that allows me to cycle through the windows that are currently open. The reason why Alt+TAB does not work for me is that I'm trying to use gestures on my touchpad (they map to shortcuts/keystrokes). So I need to be able to have a gesture that always goes to the "next" window, or else I'm stuck cycling between the most recent two.
Does such a shortcut exist?
EDIT: I'm currently using fusuma (https://github.com/iberianpig/fusuma), which itself uses xdotool
