* A word (or two) about SOFTCODES. Their main purpose is to provide a naming convention for machine-specific
* controls, without tying us to any particular keyboard mapping. They are used in two main ways.
*
* First, if we have a binding to the machine's "screen", there will, at a minimum, be onkeydown and onkeyup
* handlers attached to the screen, and those handlers will need to iterate through the SOFTCODES table, looking
* for key codes that we care about and converting them to corresponding soft codes. Some machines, like
* Space Invaders, will then act directly upon the soft code (eg, converting it to a machine-specific status bit).
*
* Second, a machine may have other bindings (eg, buttons) to one or more of these soft codes, and those bindings
* will need to know which key codes they're supposed to generate. Some machines, like the VT100, will then use
* another table (KEYMAP) to convert key codes into a machine-specific "key addresses".
