How do I MS Word to automatically capitalize the first word of each line?

I use Dragon Naturally Speaking 8 & every time I say "New line," I have to say "Cap" before the word I want to say. I'm writing poetry & need to capitalize that first word.
Update: Actually, I only want the first letter of that first word! Oops! Someone told me how to do it, but I got a new computer & forgot how.
