For most Metadata Types you will just need to select the Metadata Type you desire and which group of packaging to get (All, Unmanaged Only, or Managed Only).
For a slect group of Metadata Types (EmailTemplate, Report, Dashboard, or Document) you are required to also select a folder as well. You can slect 1-3 folders at a time.
If you select another without a folder usage then this is your final selection set screen. Package Types allow three options (All, Managed, Unmanaged).
Finally you will be presented with results after clicking "Search". Selecting a metadata value will make "Package XML" and "CLI Reference Command" panels become visible. You have the ability to copy using buttons. Package.xml offers the ability to copy full file or just the types group if you are looking to add to an existing package.xml file locally.
