Use the document to learn how to work with the History panel
Scroll through the History panel using the arrows at the ends of the panel. Alternatively, you can drag the versions inside the panel to scroll them.
You can search versions based on their version name, description, cast list, version number, created by, and time stamp. Enter text in the search box within the History panel. The relevant versions are displayed.
Click the delete (trash) icon to delete the corresponding version. Version numbers of other versions are unaffected.
You cannot delete the current version of a document.
