If you own an Apple TV, there are some hidden features on how to use it that aren't found in the User Guide that comes with the Apple TV, and they are not even mentioned in the online manual that Apple provides. Take Control Books has a handy one page cheat sheet that reveals all the tips. Three handy tips include 1) resetting your Apple TV (without doing a power cycle), 2) putting your Apple TV to sleep (without waiting for one hour), and 3) quickly getting back to the main menu from deep into the menu layers.
If you want the full 197 page booklet by Take Control Books, there is a link in the cheat sheet to take you there. Don't forget to use the discount code.
