Otherwise, if forgive is true, then unknown keys simply don't produce any values. Otherwise, if default and defaults are None, and forgive is false, then the unknown keys will probably raise an exception through valueForUnknownKey() although that method can always return a final, default value. if keys is None, then None is returned. If keys is an empty list, then None is returned. Often these last four arguments are specified by key.
