What these do[]

I came here to find out what these do, what exactly they're used for and when to use them. Unfortunately, this page didn't provide the information. NibKing (talk) 23:30, April 24, 2014 (UTC)

Good point. I added some info that should be helpful. Continue to complain, if it isn't good enough. --
