What's the correct method for itallicizing on facebook?

None of the HTML codes work in status updates. They all work in Notes (see a href="https://www.facebook.com/notes_cheatsheet.php" rel="nofollow"https://www.facebook.com/notes_cheatshee…/a ), and *bold* and _underline_ work in Chat. (Use the asterisks and underscores to indicate bold\underline.)
