# [IPython-dev] Latex highlighting for markdown cells?

Here is an example of the codemirror overlay with IPython's mode:

https://bitbucket.org/ipre/calico/src/master/notebooks/nbextensions/calico-spell-check.js

That code is a little bit complicated as it has a function, makeOverlay,
that makes a function overlay. That is so you can make spell-check overlays
for as many modes as you want.

BTW, this appears that it will need some changes to work with
IPython3/Jupyter.

Hope that helps,

-Doug
