This interface offers the following buttons:
Edit document () - redirects you to the document's editing interface in the Content -> Edit section of CMS Desk
Navigate to document () - opens the document in a preview mode in a new browser window
The icon in the header of the Actions column displays a context menu offering options for export of listed data to various types of files.
