How to turn off "shouts"

OK, I've disabled emotes and "local" chat. Now, how do I turn off "shouts"?
When I'm in town, I don't really care to see dozens and dozens of WTS and WTB shouts. It's hard to keep track of a real conversation.

Thanks.

As in trade chat?

As in the little word bubbles above people's heads when they use local or team chat, that cannot be disabled.

ctrl+shift+h

:P

Well yes, of course...but who would want to close the entire UI when playing?

well ive usually got the same skills on the same spots so it can be done :P

Hmmmm...close your eyes?

How do the little cartoon bubbles affect your conversations in chat?

Sorry, I was referring to Trade Chat. I didn't realize that's what it was, and now I feel stupid.

Thanks!
