/*
Mac OS X uses its own set of hardware key codes that are different from PC keyboard scancodes, but are positional (like PC keyboard scancodes). These are defined in <HIToolbox/Events.h>, a Carbon header. As far as I can tell, there's no way to include this header without either using an absolute path or linking Carbon into the program, so the constant values are used here instead.
The Cocoa docs do guarantee that -[NSEvent keyCode] results in key codes that are the same as those returned by Carbon; that is, these codes.
