If you know how to do this, I would indeed be interested. I already pondered if it wouldn't be possible to merge multiple "folding strategies" if one would build some kind of interface with which multiple routines could basically communicate folds in a buffer. Say you have one routine scanning the syntax of the according language, one looking for folding markers and one for manual (Vim-style) folds. I guess it technically should be trivial to use all of them provided they are nested and don't intersect in weird ways (the latter could be resolved with some simple priorities).

I wound up not getting the computer out. Looking at it right now to see if it would be as easy as I was thinking. Simply put, knowing how advanced org-mode can get with folds, this is likely trivial to do. (If you haven't played with it, I'd recommend taking a look. I don't have perfect examples, but http://taeric.github.io/DancingLinks.org http://taeric.github.io/DancingLinks.org is an example. Open that in emacs with org-mode and you will see that all of the source blocks can be folded together. For me, the source blocks are correctly colored, as well.) Quickly searching, I found https://www.emacswiki.org/emacs/FoldingMode https://www.emacswiki.org/emacs/FoldingMode, which seems to be a large start to this. There were also some other ideas that seem to get close. The basic idea I had was to just make a few functions that would: - Fold from current location to next #endregion - List all region/endregion's in the current buffer - Fold all region/endregion's in the current buffer The second of those felt trivial, since it is basically M-x occur #region\|#endregion. On top of that, I just need to learn how to actually make overlays and then the rest feels like it would fall into place easily enough. Edit: It occurs to me that I didn't show how to actually hide text, which I think is your question. Fastest way I can see is this (run this in your scratch buffer to see it in action): (let ((o (make-overlay 5 120))) (overlay-put o 'display "---hidden---")) To easily delete this particular overlay, if you make it, use: (let ((o (overlays-at 5))) (mapcar 'delete-overlay o)) So, the basic task that will need to be completed is finding the point position for the start and end of make-overlay.
