Wow, thanks for that complete code. I didn't know about the parse tree
functions.

I was thinking if below is possible as any user running my exporter
would need to use this feature easily.

#+begin_katex :verbatim t
E = -J \sum_{i=1}^N s_i s_{i+1}
#+end_katex

Is it possible to do anything inside the org-hugo-special-block
function that's defined in the exporter?
