Oops! I switched this on and now can't figure out how to turn it off?!

I don't know where the option is to switch these things back off. I've been all over the control panel, there is so much in there and easy to get lost. Anyone know where these controls are so I can get rid of this showing up?

I finally found it. I was looking under options, but it actually was sitting under style properties: message elements.
