If a [default preset](/plugins/introduction-to-plugins/plugin-configuration-and-preset-management.md) has been set for the plugin, the button will be clickable, and clicking on it once will run the plugin on the current asset with the default settings.

Clicking on the three dots next to the model name will open the Model Run Dialog, allowing you to customize the plugin's run settings and to run the plugin on the current asset with settings of your choice.

The *Compile as LaTeX* button will take the text content of the current asset and treat it as LaTeX markup, then attempt to compile the document. If compilation was successful, it will display the resulting PDF. Through the option toggles, you may ask Ango Hub to wrap the text with a document environment (i.e. `\begin{document}` and `\end{document}`) and to add a document-type class.

## How to Annotate Markdown <a href="#how-to-annotate-text" id="how-to-annotate-text"></a>

In Markdown assets, only classifications are available.

From the *Classifications* panel on the left sidebar, answer the classification questions. When done, click on *Submit* on the top-right corner of the screen.

### Keyboard Shortcuts <a href="#keyboard-shortcuts" id="keyboard-shortcuts"></a>

A full list of keyboard shortcuts is available by clicking on the *Keyboard* button on the right side of the top bar:
