In the Metatag module UI it uses tokens but only shows a small list of tokens that are relative to the site information rather than the full content tokens which it can use, in D7 there was an admin token page so you can check values.
Where is this in Drupal 8?
I see its one of those things that you once you know.
Enable modules:
Navigate to the page: /admin/help/token.
node or block are unlikely to know which node or block you're referring to.
