Use all of Emacs’s modifiers on macOS with various keyboards.

When non-Emacs users observe Emacs users laboring over their key binding configuration their typical range of reactions include finding it to be interesting, surprising, remarkable, strange, weird, incredible, striking, bizarre, deviant, eccentric, freakish, monstrous, incomprehensible, inconceivable, incredible, unimaginable, and unthinkable. With that range reactions in mind it is self-evident that if you are reading this then you already know why you want to use more of the Emacs’s modifier keys you just want to know how. The purpose of this project is to capture one way of using all of Emacs’s modifier keys.
