## Emoji

Comments have emoji support! If you are using a Mac, you can activate the emoji menu with command + control + space.

## Mathematical expressions

Comments in Crowdmark support LaTeX expressions using MathJax. This allows graders to write mathematical expressions. Inline mathematical expressions can be created by wrapping LaTeX with single dollar signs and displayed mathematical expressions can be created by wrapping with double dollar signs. We thank the developers of MathJax for making this possible.

Example:

$$\zeta (s) = \sum_{n=1}^\infty \frac{1}{n^s}$$

## Chemical expressions

We are grateful to the developers of the mhchem package in MathJax for making this possible.

Example:

$$\ce{SO4^2- + Ba^2+ -> BaSO4 v}$$
