I think I have now figured this one out. Changing the

That is not true. As Alex explained, when you modify the keymap, you
are modifying a part of its list structure that is shared by the
variable and the mode.
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.
Ah, I didn't realize that.
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.
Sorry, I was the dense one. You are correct.
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?
It would.
