No standard way.  It would be nice to have a redirection mechanism.

Admittedly, the TOOLKIT EXT wordset is not the ideal place for it.

However, note that it is possible to "mix and match" words from the EXT
portion of wordsets.  The "base" parts of wordsets are supposed to come
as a bundle, but the words in the EXT parts can be supplied on an
individual basis.  Consequently, the fact that SEE and EMIT? are in the
same EXT wordset doesn't "couple" them.

As a matter of fact, ALL the words in the TOOLKIT wordset were moved to
the TOOLKIT EXT wordset to remove any coupling between them.

FORTH-WORDLIST is the "wordlist identifier" of the FORTH vocabulary.  It
leaves that identifier on the stack, where it can be used as an argument
to SET-ORDER , SET-CURRENT , or SEARCH-WORDLIST .

FORTH is still there, in SEARCH ORDER EXT.  FORTH does the usual thing
of putting itself in the search order.
