I guess so if that makes sense to do farther down the track. The advantage to using rx is to avoid those repeating pathological toothpick sequences that are difficult to track. For now, highlight-rx for searching is enough. > But the documentation says: > > The =E2=80=98rx=E2=80=99 notation is mainly useful in Lisp code; it = cannot be used in > most interactive situations where a regexp is requested, such as when > running =E2=80=98query-replace-regexp=E2=80=99 or in variable customisa= tion. For search and replace, I don't know if it would be possible to use in org-mode in the future, say, a table of three columns having 1. input pattern 2. output 'desired' pattern 3. rx pattern which is generated automatically for 2 >> At the limit there are things expressible in regexp that rx won't be >> able to.

I guess the rx keywords will evolve to fit better with experience. Statistics are beginning to be collected on the reported bugs. Perhaps, rx can be used there where it makes sense.
