What is the "CC" icon up in the top left-hand side of the screen for?

Click on it to turn on "Closed Captioning" (subtitles) so that you may

read along with the action. This is a very handy feature for the hearing

impaired or the soundcardless (or those of you who aren't allowed to

have the speakers turned up when it's well past your bedtime).

Note: To turn it off - just click the "CC" again.
