And I'll add another one you can mix in there, and that's the colon! It's great for when an item is actually several items, like several paragraphs for the same item (e.g. a list of instructional steps). It's also great when you want to add a note to an item, using # for the item then #: for the associated note. Or when the section is all using the leading colon and you want to insert a numbered or bulleted list (:#, :*).
You do have to be really careful mixing #, *, and : though. If you insert even one wrongly, then the numbered list is renumbered from one at that point. I've been so frustrated at times when writing up a step by step procedure, to finally get it formatted the way I wanted, preview it, and discover it's one long nicely formatted list of items - all numbered 1! And it's also easy to mess up later, when you want to add a note (e.g. perhaps a note deprecating a step, or noting a later revision), and discovering you just renumbered part of the list. Once in awhile, I would have to give up on # and hard code the numbers.
