    left / right / a / d	rotates avatar left / right, strafes in mouselook
	shifted version turns the avatar to walk sideways, so not really a strafe.
	So not sure if the "strafe" in mouse look turns the avatar as well?

    Mouse look is just first person view, moving mouse looks left / right / up / down.
	Not sure if the avatar rotates with left / right, but that's likely.

    ctrl			Nothing?
    shift			Nothing?
    ctrl shift			Nothing?

    Need to also consider when looking at a moving object / avatar.

    I think there are other letter keys that duplicate arrow keys and such.  I'll look for them later, but I don't use them.
    No idea what the function keys are mapped to, but think it's various non camera stuff.
    I'm damn well leaving the Win/Command and Menu keys for the OS / window manager.  lol
    Keypad keys?  Not interested, I don't have them.
    Print Screen / SysRq, Pause / Break, other oddball keys, also not interested.
    NOTE - gonna have an easily programmable "bind key to command" thingy, like E17s, so that can deal with other keys.
	Should even let them be saveable so people can swap them with other people easily.

    TODO - implement things like space mouse, sixaxis, phone as controller, joysticks, data gloves, etc.
