[Newbies] Howto find all subclass responsibilities for a given Class

  You can happily evaluate the following:

  Morph new openInHand

and the instance of Morph is fully operational in the system.  This
means that you don't have to treat it as an
abstract class; it is a concrete class from which you can make your
own subclasses.

  For a search, you can do:

(SystemNavigation default allCallsOn: #subclassResponsibility)
	select: [:ref | ref classSymbol = #Morph]

and you don't get any, I believe.
