pyWinHook (Hooking keyboard input for shortcuts)

This works to block keyboard input for various keys! It uses an updated version of pyhook (pyWinhook) to block modifer keys and such, then present them to the program. Next steps are making that toggle whether or not the KVM window is focused!

    if event.Key.lower() in ['lwin', 'tab', 'lmenu']:
        return False    # block these keys
    else:
        # return True to pass the event to other handlers
        return True
 
# create a hook manager
hm = pyWinhook.HookManager()
# watch for all keyboard events
hm.KeyDown = OnKeyboardEvent
# set the hook
hm.HookKeyboard()
 
# initialize pygame and start the game loop
pygame.init()
 
while(1):
    pygame.event.pump()

this works, but next steps are to make it register on both key up and key down - right now, it’s juts key down, and I need to pass the events properly. look at https://pyhook.sourceforge.net/doc_1.5.0/pyhook.HookManager.KeyboardEvent-class.html#IsTransition in the docs!
