If you are using pywin32 you should be able to fine the GetMessage, DispatchMessage, and TranslateMessage functions in win32event module.
One continuing problem I've had though is that some key events don't seem to be working correctly. I have the SpaceExplorer - the model with the second most buttons BTW. I'm guessing that the esc, ctrl, etc keys are generating normal keycodes like a keyboard? What are the key codes for 2d and 'fit' though. I think 32 is the keycode for 'fit', but keyboard.GetKeyName(code) raises a undefined COM error?
