Because the purpose of cursor-intangible-mode and cursor-sensor-mode is to make the `intangible`, `point-entered`, and `point-left` properties (along with inhibit-point-motion-hooks variable) obsolete. > When implemented it could treat the text that has the 'invisible' > property by expanding when cursor moves inside, and then contracting > when it's out again like is demonstrated in > https://debbugs.gnu.org/35624#104 It's called `reveal-mode` (and no, currently it doesn't work with text-properties, only with overlays. Still waiting for someone to write the code for that). > Another case where such mode could help that comes to mind is the > grep-find-abbreviate feature, where instead of pushing the button > to expand/contract the hidden part enabling cursor-invisible-mode > could expand/contract it when the cursor moves inside. It seems cursor-sensor-mode could also be a good fit for this one. Stefan
