Turn notes are entered using a plaintext box, but later rendered as HTML, so formatting is not possible unless you either:
a) write the markup by hand
b) reopen the brewnote from the Batch page; this opens it in a WYSIWYG editor (which allows direct HTML input).
The overlay on the batch page should be able to read the raw text of the note and adjust the DOM using a markdown-to-html library
