What we had in the past is because of an obscure internal, undocumented implementation detail of how Emacs adjusts point when it ends up inside invisible region: /* If the preceding character is both intangible and invisible, and the invisible property is `rear-sticky', perturb it so that the search starts one character earlier -- this ensures that point can never move to the end of an invisible/ intangible/rear-sticky region. */ Except that we do not have intanglible property there and the code below that comment does not always check for intanglible property. > OTOH, to fix my bug, only the first of the new `org-rear-nonsticky-at' > calls is actually needed. So probably we could have something like the > following to get my bug fixed without any changes in behavior (diff on > top of main, that is, in addition to your commit): I am not sure if it is a proper fix. The basic problem is that Org's syntax table does not declare emphasis markup as part of a word.

Previously, the SPC would just move the whole >> emphasized word one space to the right. Which I somehow got used to, >> and probably many others as well. The root cause revealed by my change is that Org mode does not always consider emphasis markers to be word boundaries. Note how when you do not hide emphasis markers, C-<left> will end up in *<point>foo* When emphasis markers are not hidden, things were the same, except that Emacs adjusted point right to sticky invisible text in the direction of point movement, leading to inconsistent behaviour between hiding and not hiding emphasis markers. Yet, Org sometimes does treat emphasis markers as word constituents: At least, `org-fill-element' and `org-transpose-words' temporarily turn emphasis markers into parts of words. The situation is clearly a bit chaotic. One of the reasons why we have such a mess is because *_/~+ are not always representing emphasis. Proper distinction between *_/~+ that are and aren't part of actual emphasis would require a custom `syntax-propertize-function' that would query Org element API to determine the context. Unfortunately, using `syntax-propertize-function' it is not very practical yet. We need parser context down to object level, while we only cache parser state down to element (paragraph) level. So, querying element API in this case will lead to significant performance degradation, with quadratic (N_objects_in_paragraph^2) complexity in some cases. I will leave this bug report open until we have a better caching and can reasonably implement custom `syntax-propertize-function'. Or, if any, please post arguments against making emphasis markers word constituents. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
