Sorry I can explain. While holding the run button (shift) it cancels the tool use. I was just wondering if possible there was some way to turn it on. Perhaps I could also make a tool go farther while running. But I could adjust that if it was possible.
Oh I think I see, I think it is because you are pressing shift so the button being sent as pressed is actually a capital letter, while your tool most likely has a lowercase letter for its key. I can add a check for both.
