Get out of MAC full screen
I play a video game (Diablo 3) which goes into the full screen mode. When I receive a message while I play the game, I used to use a keyboard shortcut (OPTION-COMMAND-MEDIA EJECT) to take control of the computer and open MAIL, but with an update of the game, I cannot exactly get out of the full screen mode. The keyboard short cut described above does not let me take control of the computer, and all the suggestions described in the Internet or Apple documents have no effect (eg. CONTROL-COMMAND-F). What is the quickest way to temporarily take command of my Mac (MACOS v.15.3)? Otherwise, I have to play the video game to a convenient place, leave the game completely and run MAIL, or the game has to be replayed.
