Though it doesn't happen often, I sometimes find myself in the situation where OSX will not respond to any commands.
The last time this happened I was closing a fullscreen VM - the app went away but then I was on an empty screen and wasn't able to switch away (the mouse still worked but not the brightness/volume keys).
Is there any way to escape from such a situation other than holding the power key?
(I only found a few shortcuts that are supposed to force quit but none of them worked. Some mentioned an "EJECT" key which I do not have on my MacBook Pro keyboard.)
