Explanation:
SelectItem is the intent, and each item below it are example utterances that capture ways users can express this intent. Entities in .lu files are denoted using {<entityName>=<labeled value>} notation. Taking from our sample code once again, you can find the bottom left entity within the following utterance: choose the {DirectionalReference=bottom left}.
