Normally, you would use “Ctrl + Alt + Break” to toggle the “Full Screen” mode within a Remote Desktop Session.
However, what if your laptop does not have a “Break Key”? How do you force Full Screen Mode in such a circumstance?
My Dell Vostro 3300 is such a machine. There isn’t a “Break” Key.
However, with a bit of playing around, I discovered that “Ctrl + Alt + Fn + F12 (Pause)” does the job.
