Anything's possible, of course. The Info file format is full of ad-hoc-ery, so Emacs generally supports only the tricks that are actually used, lest we cause some unintended harm in some unusual file. If the Texinfo developers decide to use quoting in more places, Emacs will follow suit. > > +2024-12-30 Gavin Smith <gavinsmith0...@gmail.com> > > + > > + ".

That is likely the best solution if Emacs would not want to support > the ^?NODENAME^? syntax. Emacs will go with whatever the Texinfo developers decide.
