Alternative ways to switch between applications if cmd+tab doesn't work What are alternative ways to switch between applications?

Cmd+Tab doesn't work for me in some games. For example on steam; "Crusader Kings II", "The Talos Principle".

So i have no ability to switch to another application like Safari when needed unless I quit the game. This is very inconvenient. 

I also tried Cmd+ H  and  Cmd+ Alt +H, they do not work either.

Cmd+ Alt +Esc force quits the game immediately.
Command+Tab doesn't work because the game is running  in Full Screen. 

In most games you can enable Window Mode within the game's Preferences and / or switch between Window Mode and Full Screen with a shortcut.

As for my experience, doing Command+M tends to do the trick.
