1. If I press a key NOT in the group, the ELSE statement is executed, but I'm getting anyway the aforementioned output error in the console, which is quite annonying.
   
2. If I press the ‘s’ key, instead Houdini would exit the viewer state and switch to the Selection State, which is understandable, being ‘s’ the hotkey for that, BUT the IF statement is not getting evaluated. So you can't know if an already assigned hotkey is being pressed in your custom node viewer state.
   

    def onKeyEvent(self, kwargs):
        ui_event = kwargs['ui_event']
        self.key_pressed = ui_event.device().keyString()
        if self.key_pressed in ('a', 's', 'shift a', 'ctrl g'):
            # returns True to consume the event
            print('key pressed')
            return True
        else:
            print('No')

I see the api provides a method for Right Mouse Button press, but again, when I click the rmb it won't trigger any event, only the context menu pops up (and won't allow any new mouse event to be logged)

    def onMouseEvent(self, kwargs):
        ui_event = kwargs['ui_event']
        print(ui_event.device().isRightButton() )

So, how to know when RMB is pressed during a python state?

thanks for any help
