I’m not sure how to look for this, but I find the behaviour of this shortcut a bit stressful. When I have more than one window in a virtul desktop, I’d like to be able to quickly move through them with Alt+Tab; my problem is that it seems that this shortcut only works for the last two used ones, and if I want to go to the third application I need to keep Alt pressed and wait for the switcher to open.
I remember an option to change this beahviour, but I don’t know where to look for it now.
