The Fn key by itself does nothing. It just changes the code sent by
the keyboard when the F8 (or whatever) key is pressed. The tricky bit
is that sometimes it's not a key that gets sent, it might be an ACPI
or WMI message (I think those are the correct acronyms). But there is
also a standard key code for monitor switching which you could map to
some other key on the external keyboard. I'm using Wayland, so xev
doesn't work for me. However, using evtest, the kernel keycode is
"KEY_SWITCHVIDEOMODE" and I think that translates to something like
"XF86VidMode" in X.

Well then the next thing I will do is see how the F8 key code changes
when Fn is pressed. It did not occur to me, I just expected Fn to be
another key code which it seems it is not. /If it will retain the
present setting through a reboot I may never have to use it.
Thanks for the explanation,
