[O] mathjax macro in org-mode

[Jeremie Juste]

Hello,

I was wondering how to set up mathjax macro in org-mode. For instance
would it be possible to use #+HTML_MATHJAX: to include the following macro?

     Macros: {
      R: '{\\mathbb{R}}',
      bold: ['{\\bf #1}',1]
    }


So far my attempts have been unsuccessful.

Best regards,

Jeremie
