Apologies if this is a FAQ, but I didn't see it in the GNU Emacs FAQ or while googling (and I have an `info` problem, about which separately):
How can I (presumably in init.el) extend my `C-x 8` keymap? E.g., I want
to
sequence produce as does (currently)
-------- ------- ------------------------------------
C-x 8 d δ C-x 8 RET GREEK SMALL LETTER DELTA
C-x 8 D Δ C-x 8 RET GREEK CAPITAL LETTER DELTA
Currently those sequences are undefined.
TIA, Tom Roche <Tom_Roche@pobox.com>

Try this:
(define-key iso-transl-ctl-x-8-map "d" [?X])
(define-key iso-transl-ctl-x-8-map "D" [?Y])
But instead of X and Y you need to use the actual chars you want.

When I do
init.el
+ (define-key iso-transl-ctl-x-8-map "d" [?δ])
+ (define-key iso-transl-ctl-x-8-map "D" [?Δ])
I get
*Backtrace*
> Debugger entered--Lisp error: (void-variable iso-transl-ctl-x-8-map)
FWIW, I'm running
$ emacs --version
GNU Emacs 23.3.1
your assistance is appreciated, Tom Roche <Tom_Roche@pobox.com>

Oh, right.
You should be able to do the same thing, but quoting the keymap var (actually, a
function that DTRT):
(define-key 'iso-transl-ctl-x-8-map "d" [?d])
(define-key 'iso-transl-ctl-x-8-map "D" [??])

+-- quote mark
If that doesn't work then try this before using the unquoted sexps:
(require 'iso-transl)

That was it! Just put that in a file loaded from init.el,
byte-compile-file, restarted emacs. For future use, this is now an
example @
