Being an old timer used to Plain TeX, I'd like to be able to add Plain TeX portions to an org-mode file and have them be nicely displayed when exported. Is it possible to configure org-mode for this to happen?

In defense of using Plain TeX within an org-mode file, I would say that Plain TeX is better suited to situations in which one just wants to add a few greek letters and/or formulas, without worriyng about the structure of the document (documentstyle and all that which standard LaTeX usually requires)

  • doesn't this just work? orgmode.org/manual/LaTeX-fragments.html

    @Tyler, I am happy with the fact that org-mode allows for LaTeX fragments, but my question was mainly about Plain TeX fragments. As an example, the perfectly good Plain TeX construct $$\matrix{x & = & y \cr a & = & b}$$ gets org-mode confused as this is not valid in LaTeX.
