With Microsoft Word 2007, how do I remove the blue (formatting) lines underneath my paragraphs/sentences?

I was able to remove them before, but now I forget if I was able to remove the formatting in the View tab. The blue lines I was refering to are akin to the green lines you'd see below a word/phrase/sentence to demark a grammatical error. Similarly, you'd see the same squiggly line in red underneath a mis-spelled word. While I'm at it, what is that squiggly line called anyhow?
