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)
