As you build your shortcut, you can search for transform actions using keywords like make, filter, convert, edit, get and adjust. For example, you might want to use Filter Images to separate portrait photos or use Make Rich Text from HTML on a link from Safari. A search using the keyword convert displays actions that perform conversion tasks.
Other helpful transform actions include Combine Text, Combine Images, Translate Text, Detect Language, Filter Event Attendees and Filter Files.
