Comment 10 for bug 537137

I too have ran into fullscreen applications where it would be convenient if the ctrl+return alt+tab or ctr+shift+esc or ctr+alt+backspace either (respectively) minimized, tabbed to the desktop or other window, killed the current fullscreen app, or brought up a task manager GUI to easily kill misbehaving apps that are taking up the full screen and grabbing the keymaps...

This mainly happened after an update broke my alsa + pulseaudio to where I had to follow these instructions http://swiss.ubuntuforums.org/showthread.php?t=1395089 to get it fixed

But now, every time I load an application the volume is set too low to hear and I need to re-adjust it. This is when I noticed that there is currently no way to exit some fullscreen games without closing the program. At least a few (such as World of Goo) allowed me to alt+return to window the application, but unfortunately some FOSS developers are not as thoughtful as 2Dboy apparently...
