The description includes this phrase:
"Gets the Key given an object that might be a Key, Key, or entity." ???
I see the "Key,Key or Entity" pattern repeated several times in this page.

Does this have some special meaning or is it simply a mass-edit gone awry?

A lot of Objectify methods (like Query.filter()) accept "key-equivalent structures". This could be an objectify generic Key<?>, a native datastore Key, or an entity with valid id/parent fields. Ofy4 will probably add Ref<?> to that list.

Internally they pretty much all run the parameter through ObjectifyFactory.getKey() or ObjectifyFactory.getRawKey() depending on what the required value is.

The documentation could be cleaner. We need a good term for "key-equivalent structure".
