I don't know how I missed that (maybe flaky pasting or typing)

I see that setupcon calls ckbcomp. So I'm assuming that the Debian Way™
is to run dpkg-reconfigure console-setup, and I see that that does do
the appending to cached_UTF-8_del.kmap.gz.

I've added the following lines to /etc/console-setup/remap.inc:
--------
# Last edited 2015-08-20
# After editing this file, run the following on a VC (making no changes):
# dpkg-reconfigure console-setup
# dpkg-reconfigure keyboard-configuration
# Ctrl-arrows do the same as PageUp/Down (for moving by word)
ctrll keycode 105 = Prior
ctrlr keycode 105 = 'z'
ctrll keycode 106 = Next
ctrlr keycode 106 = 'Hello'
#
--------
... and then run dpkg-reconfigure as in the comments. This has an
immediate effect which is rather bizarre: Alt-Left and Alt-Right
(which I use in iceweasel as GoBack and GoForward) now rotate the
display through the VCs, including X. As you know, normally you
can rotate into X but not out of it, which requires CtrlAltF{2-6}.
Note that this bizarre behaviour only happens if X was running (on
VC1) while I was dpkg-reconfiguring on VC2.

No. I reboot, and that also has the benefit of eliminating the
bizarre effect above. Bear in mind that I'm not trying to make
two configurations to switch between. I going for a single stable
configuration that comes up at boot.
Anyway, something gets seriously screwed up by adding those
lines. They have no effect on either Control-. However, WindowsL-Left and
-Right no longer behave as normal (ie rotating VCs), so I have to use
Alt-. Without those lines I can use either modifier to rotate through
the VCs. But worse, the keyboard has gone american: < > left of z
(instead of \ |), \ | left of Return (instead of # ~) and so on.
Normality is restored by removing the appended lines and dpkg-reconfiguring.
The output from dumpkeys -f is very different in the two
cases. Here are the first two lines (spaces have been compacted):
With the extra lines:
keymaps 0-2,4-5,8,12
keycode 1 = Escape Escape VoidSymbol VoidSymbol VoidSymbol Meta_Escape
VoidSymbol
As normal, without the extra lines:
keymaps 0-127
keycode 1 = Escape Escape Escape Escape Escape Escape Escape Escape Meta_Escape
Meta_Escape Meta_Escape
Meta_Escape Meta_Escape Meta_Escape Meta_Escape Meta_Escape Escape Escape
Escape Escape Escape Escape Escape
Escape Meta_Escape Meta_Escape Meta_Escape Meta_Escape Meta_Escape Meta_Escape

[I've wrapped that line just to be polite]
Further down the file, you can see the changes that have put the
keyboard into US-English instead of GB. I can't work out how adding
four lines can make all those undesired changes (and no desired ones).
Cheers,
David.
