[-- Attachment #1: Type: text/plain, Size: 706 bytes --] In a minor mode I wrote for myself, I use add-text-properties to make certain things invisible. This does not work in org-mode, and I don't understand why. For instance, the following has no effect in when the buffer is in org-mode (and only when it's in org mode): (add-text-properties 1 3 '(invisible t)) Any other text property I try to add does not give me any problem. I have also tried to achieve the same by adding things to buffer-invisibility-spec, but again, the following has no effect whatsoever, if in org-mode: (add-text-properties 1 3 '(invisible hide-this-stuff)) (add-to-invisibility-spec '(hide-this-stuff)) Can anyone give me a hint as to what is going on? Thank you. [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 857 bytes --]

This is because Org makes use of invisible text property during
fontification. You should either apply invisibility in Org through
font-lock, or do it temporarily until next re-fontification via
(with-silent-modifications (add-text-properties 1 3 '(invisible t)))
Best,

At some point I figured I had to actually study font-lock and I did solve it, with font-lock-add-keywords.
