I'll toss in about the arm position toggling. I don't think this would be too much of a stretch, but it'd depend on how you implemented it. If you counted how many times the toggle button was pressed, it'd be illegal because it'd depend on a software state. I think it'd be legal if it started a "move arm" routine that depended on the physical position of the arm. Obviously this sounds a lot like arguing semantics, but I think it makes sense.
