I meant both. I see that neither accomplishes what I wanted, i.e., for the folded indent to display as indented. As it is, it appears to me that the only way to know a fold is indented is to undent it.

But having tried that I see that that would not have accomplished what I wanted anyway, i.e., for all text with a certain range of a given line to "disappear under" that line. But I see that there is a way that can be done, by folding the other lines first, then folding on the first line and the lines that have already been folded.

I just wish I could get rid of the prefix that indicates how many lines there are in the fold. No doubt that is useful to some. To me it is clutter. It just gets in the way. The text of the top level line is sufficient to identify what's in the fold as far as I'm concerned.

I've done that. The options you suggest either don't do what I want, i.e., to display all and screen lines of an indented text, and only those lines as indented; or do things I don't want, e.g., insert hard returns into the text.

That said, I've come to the conclusion that I don't need to do what I wanted to do, that the method of "folding on folds" will accomplish most of what I wanted.

Sounds like that would do the job. Especially if I could do it on a per file basis, i.e., without specifying filetypes to which it applies or having it apply globally.

I'll read up on the command, and will probably have more questions after that.

Thanks for the informative response to my noobie questions.
