Is it possible to automatically exit full-screen mode in Safari on cmd-tab press? I have a problem that while watching videos in Safari in full-screen, I need to access another program, but at the same time keep watching the video, in not-full-screen mode though. Currently if I cmd-tab from full-screen of Safari to another program, that covers only a part of the screen,
I get this in my Safari window:


How can I switch to non-full-screen move automatically after using the combination of alt+tab?
Or is there any alternative that could be tailored to my need?
As far as I understand your problem, when you are in full screen video, you can switch to normal video size by ⌃⌘F

(And switch between Apps by ⌘TAB, not ⌥TAB)
