With the 'Scenes' button on the left side of your screen, you can see an overview of all the scenes that are in the page. Scenes are slides inside a page where you can put more content to tell your story. You can create links to every scene or you can link to the next and previous scene easily by just selecting those options in the link panel.
In the scenes panel you can add or delete scenes, reorganise them and set them to be sticky etc. Read more about these options in the article Pro - Split your story in scenes
