Theres the big arrow beside your selected shout but what does the little triangle mean?

Is it selected as your one of your favorites?

Yup. Brain fart!

Interesting.
In your equipment inventory it usually means an item is better than the one you have quipped.
Not sure for the shouts though.

Ah yes, its a favourite.

Glad I could help

You must have been up all night playing Skyrim and tired to have made that brain fart. I heard that one all the way over here in the Rotten Apple that never sleeps...
