What are Tags?
Tags are another method of organizing your timeline. You can add tags to events using the Tags heading in the Inspector. Tags must be unique and cannot be empty.
To add a new tag, tap on the Tags heading in the inspector and type the tag name in the search bar. Tap on the created tag in the list below to create the new tag and add it to the selected event. To add an existing tag, simply select it from the tag list.
