Then I still do not understand how to get emacs to use
the revised keymap.  For one thing I am not modifying
_the_ keymap - I am creating a new one.  I am sorry if
I am being a bit dense here.  I think the implication
must be that replacing the map pointed to by my
variable still leaves the system with a pointer to the
old cdr.  So are you saying that it is essential to
replace the cdr _in_ the old list, as opposed to
replacing the entire list itself?

Eg., (setf (cdr my-map) (cdr new-map)), as opposed to
(setq my-map new-map).

Why wouldn't invoking use-local-map again also
accomplish the same goal?
