Those seem to be in order. I can confirm that the key actions do in fact work, however, it's not clear what you are trying to do in context.
Does the, 'move right' command work if you say, 'stop' first? If so, you need to make your, 'move right command' release all arrow keys first and then press down right. If not, you're going to want to try putting pauses between your actions. 0.1 would be a good place to start.
Hope that helps!
