Quick shut down or restart!
A great tip submitted by Diego Carmona: quick shut down or restart! This is a pretty cool keyboard shortcut that shuts down or restarts the computer without going through the dialog box that asks if you want to sleep, restart or shut down. The running applications will still ask if you want to save before quitting. To shut down, you simply have to press "Control-Option-Command-Eject" and to restart, its "Control-Command-Eject". You can also get the dialog box with "Control-Eject". The sleep shortcut is "Option-Command-Eject". Thanks Diego for the great tip!
