Scripts and URLs
Mobile Celestia has the same support for scripts and URLs as desktop Celestia.
Favorites -> Scripts lists all the Celestia's built in scripts and scripts in the public folder. To learn how to put scripts in the public folder, go to Use Add-ons and Scripts.
Mobile Celestia can also open scripts directly, open your file browser and find a .cel/.celx file, you should be able to choose to open it in Celestia.
URLs can be opened in the same way, type an cel:// URL in the address bar in the web browser, the system should prompt you to open the URL in Celestia.
