On this tab, you can see a list of documents (pages) that are using the page template. By clicking a document in the list, you will be redirected to the document's CMS Desk -> Edit mode.

 

The documents in the list can be filtered according to the Site they are on, their Document name and their Document type. After clicking the icon in the header of the Actions column, a context menu is displayed, offering options for export of listed data to various types of files.
