MoveMap.bindCmd list of options?

I've tried searching for documentation on moveMap.bindCmd both in the TGB reference and online, but haven't found anything so far. What I want to know is the list of possible values I can pass for keyboard, joystick, or (???) for all the various possible things on a keyboard/joystick or other input device.

For example, is there a way to bind the Control/Option/Command keys? What about shift or caps lock?

Fortunately, I found the ones for the arrow keys -- they're just "up" "down" and so on. But what about numeric keypad? Or joystick buttons?

There's got to a complete list somewhere...
