Thanks, Chris. It depends on the filetype. If it's markdown the result is "foldmethod=expr." Otherwise "foldmethod=manual." > The script sets the fdm option to ‘expr’ for the current buffer/window, > which amounts to running user-written code for each line in the buffer. > > In this particular case, the user-written code is a function named > ‘Foldexpr_markdown()’.

At least that's the way I understand it. There are two types of markdown headers, Setext and atx. Setext uses equal sign or single underline underlining. atx uses hashmarks, #, ##, etc. I use the latter and the script folds on them fine. >> Maybe this is something Vlad overlooked?

Not a programmer. Since the script controls folding on markdown files I would look to it for an explanation. My guess about what's going on when a script or plugin seems not to be working as it should is often completely wrong. > What exactly do you mean by ‘when I create a file’..? How does it ‘not > work’? I start with an empty window, i.e., no file loaded. I type in a "#" and some text, do a <CR> and some more text, another <CR> and some more text, then write/save the file as a markdown file, i.e., with markdown extent. At that point the header is not highlighted and folding does not work. If I close the file and reopen it, highlighting and folding work.
