Bold and italic tags are converted using the asterisk syntax by default.

As an aside, I'm not sure that the phrasing "underlined syntax" is accurate. Wouldn't it be more accurate to call it "underscore syntax"? Sorry, not trying to be pedantic, just looking to avoid confusion with "syntax for underline". I'm not sure what the established terminology is in this case. I think the example makes it clear in either case.
