Click anywhere on the assessment page to open up a comment field. A comment can be dragged and dropped to another location on the page.

Comments can also be added in advance (without attaching them to a page) using the comment library. See Managing comments to learn more.

## Formatting

The comment field supports Markdown, which allows you to change text formatting and to add links and images.

Some examples:

Markdown |
Formatted |
---|---|

*italics* | italics |

**bold** | bold |

## Heading | Heading |

[Purdue Owl](https://owl.english.purdue.edu/owl/) | Purdue Owl |

![Crowdmark logo](https://crowdmark-com.s3.amazonaws.com/website/images/logo.png) | with alt text "Crowdmark logo" |

The Markdown guide contains a full list of formatting options.

## 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:**

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

**Example:**

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