# Feature Request for Note: LaTeX math formula support via KaTeX

edited October 13, 2017
In this version Zotero 5.0.22, the Note can not display math formula in LaTeX syntax.
I am wondering if Note can support LaTeX syntax for math formula via KaTeX.

For example, automatically include KaTeX in Note from CDN via:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.9.0-alpha/katex.min.css"; integrity="sha384-FkMHIpkXHDi3o2XSOOa5/9TpXg4AX4DXPSC6z28hi2Eqn/27ea8MTV18rTq9OyQR" crossorigin="anonymous"><script src="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.9.0-alpha/katex.min.js"; integrity="sha384-wt0V9VomB0kx/jgLEkR18Slo+aNALuRwOOrWkicjQ0HHpFqu0JKzaFkbtmsku5a/" crossorigin="anonymous"></script>

Does this possible to be supported in Note?

Many thanks for the great efforts that have been and still being put in developing a better Zotero.
• Sorry, the discussion does not display the code.

KaTeX and its usage can be found at: https://github.com/Khan/KaTeX#user-content-usage
• (You can put code with <code> tags. I've fixed it for you above.)

If we supported anything, I suspect it would be MathJax, which as I understand it supports a variety of input formats (including LaTeX), not KaTeX.

* It seems that "KaTeX" has a much superior performance than "MathJax".
* But I do not know if "KaTeX" has a larger support set of LaTeX syntax than "MathJax".

It may contain some information that could be useful, for example, Georg-Git has given a possible solution to make tinymce support LaTeX syntax via "KaTeX".
