I never had the idea to press the escape key

He he,

the thing is that when working with a multiple monitor setup, one might find oneself watching a video at youtube while waiting for the rendering to finish, and one might at times be tempted to watch a video in fullscreen modus. And to escape the fullscreen modus, one has to press ... Escape! And if the wrong screen is active, like f.i. the rendering screen; pressing escape will shut down the renderer.

Thanx a bunch for the link !
