Further, I just copied the "us" file, gave it a custom name, and
modified the first "key <TLDE> ..." line to read as follows:
key <TLDE> { [ grave, asciitilde, function, U266E ] };
and also added the following line to the bottom of that first section
in that file:
include "level3(lwin_switch)"
Additionally ("of course") I added a "layout" entry to the file:
/usr/share/X11/xkb/rules/base/evdev.xml (or "base.xml" - they look
the same, dunno what's the diff sorry);
edited:
/etc/default/keyboard
XKBLAYOUT="mycustomlayoutfilename"
XKBVARIANT="basic" # needed ??
XKBOPTIONS="lv3:lwin_switch,terminate:ctrl_alt_bksp"
ran:
sudo setupcon
sudo dpkg-reconfigure xkb-data keyboard-configuration
double-checked /etc/default/keyboard and re-ran setupcon,
and finally rebooted.
Nothing to it (at least not after you've tried many combinations,
searched and read a lot, and rebooted more times than my second
memory cell is capable of remembering :)
