This morning, I had Virtual Box in full screen mode on my Windows desktop, and I forgot the keystroke to get out. The typical key combos didn’t work. Strangely, I couldn’t find anything on Google or Virtual Box’s user guide that told me how to get out of full screen. Of course, it tells you how to get out when you go to full screen mode, but if you don’t pay attention (or forget), good luck finding it after the fact. Luckily, I have Virtual Box on my laptop as well, so I had a backup.
So anyone out there looking for it, that stumbled across this post… here ya go: Host + F (Host = Right-Ctrl)
