Sorry for the delay replying, but in view of my managing to get
stretch installed on the last of my machines, and with buster
coming up, I'd thought I'd do a bit of tidying.

The starting point for what I do is the composed characters that are
provided in X from /usr/share/X11/locale/en_US.UTF-8/Compose. So I
attempt to provide the same sequences to get the same characters on
the VC, just for ones that I personally use a lot.

The definitions go into /etc/console-setup/remap.inc, but AIUI you
have to include any default ones (which are mainly those for European
languages's diacriticals) because remap.inc overwrites them. I'm not
certain where the master list is, so   dumpkeys --compose-only   on
an unmodified system is the easiest way I've found to pick them up.

I failed to duplicate the X sequences for one or two characters,
I think because you're limited to two keystrokes after the Compose,
and possibly also to the Basic Multilingual Plane of Unicode. So,
for example, I use -- and __ on VCs in place of --. and --- on X
for the en and em dashes.

Then there are some common characters that aren't defined in X, so
I put those in ~/.XCompose (with matching ones in remap.inc). Again,
you have to respecify the system defaults, but in .XCompose you can
do it with an include (saving 6000 lines).

I also have a few more exotic characters that are only defined in
emacs using its ^X8 method, like diagonal, double, and double-headed
arrows.

All these work pretty much the same across all my machines/keyboards
(though I don't need £ and ¬ on my British ones). However, the fvwm
definitions vary much more because I try to match keys' functions
mnemonically with keycap engravings, and the latter vary widely,
particularly the coloured Fn keys on laptops.

So, for example, typing Sh-Alt-[☼+] or [☼-] (where Fn-[☼+] and [☼-]
increase and decrease brightness) starts or stops ffmpeg recording
of the whole screen as a movie, and Alt-[□■] (I don't remember what
Fn-[□■] is supposed to do) takes a screenshot of the whole screen.
Adding Shift- to the latter takes the screenshot after a delay.
Most keyboards have audio keys which X can recognise.

So my fvwm configuration files contains lines like:

Key	F1	A	C	Exec exec amixer -c 1 -- sset Master 0 mute
Key	F1	A	S	Exec exec amixer -c 1 -- sset Speaker 0 mute
Key	F1	A	CS	Exec exec amixer -c 1 -- sset Headphone 0 mute
Key	F2	A	C	Exec exec amixer -c 1 -- sset Master 5%- unmute
Key	F2	A	S	Exec exec amixer -c 1 -- sset Speaker 5%- unmute
Key	F2	A	CS	Exec exec amixer -c 1 -- sset Headphone 5%- unmute
Key	F3	A	C	Exec exec amixer -c 1 -- sset Master 5%+ unmute
Key	F3	A	S	Exec exec amixer -c 1 -- sset Speaker 5%+ unmute
Key	F3	A	CS	Exec exec amixer -c 1 -- sset Headphone 5%+ unmute

Key	F10	A	4	Maximize 100 100
Key	F10	A	M	Exec exec myfvwm-scrot-key-png.sh
Key	F10	A	SM	Exec exec myfvwm-scrot-key-png-delayed.sh
Key	F10	R	M	Exec exec myfvwm-scrot-key-root-png.sh
Key	F10	R	SM	Exec exec myfvwm-scrot-key-root-png-delayed.sh
Key	F11	A	4	Raise
Key	F11	A	M	-
Key	F11	A	SM	Exec exec myfvwm-killcapture.sh
Key	F12	A	4	Stick
Key	F12	A	M	-
Key	F12	A	SM	Exec exec myfvwm-capture.sh

# This performs Left/Right mouse clicks in an application (W: specifically for the browser,
# R: Left click in Root, but also activates Ctrl-Right click in Root!)
Key	Print	WR	N	FakeClick depth 0 press 1 wait 25 release 1
Key	Print	W	C	FakeClick depth 0 press 3 wait 25 release 3

I've attached some files mentioned.

Cheers,
David.
