Maybe (probably?) not what you are looking for but if you want something that meets the output requirements for LaTeX export (i.e. to PDF), you can use the =mhchem= package [1] and typing \(\ce{^{21}Ne}\) and \(\ce{^{3}He}\) will generate what you want. No special editing unfortunately. HTH, eric Footnotes: [1] https://www.ctan.org/pkg/mhchem?lang=en -- : Eric S Fraga via Emacs 28.0.50, Org release_9.3.6-316-g5dd772
