<ul>
<li>
You can add entries like `\ZZ`, `\mathbb{Z}`, which will render as <$latex text="\mathbb{Z}"/>.
</li>
<li>
An entry mapping `\dd#1#2` to `\frac{d#1}{d#2}` will create a macro with two arguments; `\dd{f}{x}` will then render as <$latex text="\frac{df}{dx}"/>.
</li>
<li>
Note that the macros defined here have higher priority than those defined using `\gdef`. Also, deleted macros will continue to exist until a full refresh.
</li>
</ul>
