# [IPython-dev] defining latex commands in notebook

I haven't used functions like this but I have found if you have a LaTex
command defined in a raw cell at the beginning of a notebook it does note
get hashed out.  I just put the following two lines in a raw cell and
converted it to check:

$\newcommand{\Mt}[1]{\mathbf{#1}}$
> \pagestyle{plain}
>

followed by a simple code cell, 2+2, and it survived the conversion.
