# Referencing Variables in Brick Configuration

### Variable References

Variables are referenced using `@` in front of the variable name. For example, a local variable `myVariable` is referenced as `@myVariable`.

### Using Autosuggest

In the Page Editor, when you type `@` into a field, the Page Editor will display the variable autocomplete popover:

<figure><img src="/files/RwZdXMinUOZOOMOfnfBh" alt=""><figcaption></figcaption></figure>

The variable popover automatically filters/expands based on the variable name under the cursor. For example, for to filter for `@form`

<figure><img src="/files/x1kLWSf4mhZoQYCqarSv" alt=""><figcaption><p>Filtering available variables based on text</p></figcaption></figure>

Alternatively, you can click the carat to expand into an object and see specific fields that exist within that object.&#x20;

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pixiebrix.com/developing-mods/developer-concepts/variables-and-data-context/referencing-variables-in-brick-configuration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
