## Font

Here you can choose the font and configure its display. Sanny Builder supports only [monospaced fonts](https://en.wikipedia.org/wiki/Monospaced_font). `AaBbCcDd` reflects selected configuration.

## Code Scan Distance

The code scanning range is used when you press `Ctrl+Space` to find [constants](https://docs.sannybuilder.com/language/data-types/constants), labels and [variables](https://docs.sannybuilder.com/language/data-types/variables). The value tells the editor how many lines to scan up and down starting from the active line. If you set a number of `0`, the editor scans the whole source file.

If the `Auto list` option is checked, the list of available labels, models and variables appears automatically as you type `@`, `$`, `#`.
