Well, you should start by identifying the fold start and stop marker.

I'm afraid there's no logical stop marker for Markdown headers, and  
since Markdown doesn't support comments (AFAIK) there's really no way  
to add it [1]

You can manually fold them though, and you can semi-automate this by  
doing something like a regexp search for: ^#+.*$(?m:.*?)(?=^#+.*$)

This should select next header, then F1 to fold that, cmd-G to select  
next, F1, …

You can record the search + fold into a macro and maybe save with a  
key. Also, TextMate will remember what you folded upon reload (unless  
you disabled FS meta data)


[1] You could of course make your own convention, and add post- 
processing to Markdown.pl
