FWIW, the config file I ended up with is below. For a good laugh,
compare it with the 300-line monstrosity your favorite distro produces
auto-magically.
Despite grub2 documentation to the contrary, 'keystatus --shift' does
not always return true if the shift key is held down. In my testing
it only returns true if shift was up when grub started and _then_ was
pressed and held down. If you press shift before grub starts (and
hold it down) then 'keystatus --shift' returns false. [Maybe this is
HW dependent?]
That's why I added the double "A above middle C" beep followed by 1
second of silence: provides a window during which you can press the
shift key. I would prefer it if you could just press and hold the
shift key immediately after power-on, but it'll do.
