I'm looking at src/stand/forth, particular, menu-commands.4th.

If the boot menu is written in lua, it's still a foreign
language to me.  So, I would need some guidance on how to
hack the menu up.

Yes, it is a convenience to have menu item.  Dropping to the
loader prompt is possible.  Taking it to a logical extreme,
let's retire the menu because everything can be set at the
loader prompt.
