Hi all,
I experimented a bit with command remapping, and it's great - but how
does it actually work? I mean, apparently it doesn't change the keymap,
and it's not stored in its symbol plist, so where is the remapping info
actually stored? IOW, what is changed when I evaluate things like
(define-key my-mode-map [remap kill-line] 'my-kill-line)
?
TIA,

The 'remap' pseudo-key works via special handling in the low-level
keymap code, see the source of where-is-internal in keymap.c (search
for "Qremap").

In the keymap.
Are you sure you have examined the right keymap and searched correctly?
These entries are not represented specially AFAIK. They are interpreted
differently, yes, but you should see entries in the keymap. Maybe you
got a submap using a `remap` prefix key?

I stand corrected, you're right, of course.
