3 keys to put your Mac to sleep
On Monday, November 3, 2008
Almost all of the time, I run my Macbook Pro in closed book mode. Once I’m done using my Mac, I like to manually put it to sleep — right then and there.

Sure, you can click the Apple in the upper left corner, and then slick Sleep, or you can use this wonderful three key combination…
They are, pressed simultaneously: Option, Command, Eject.
To wait up your computer, simply move your mouse, or press your Space Bar.
Enjoy!
