The only thing I would change is the caps. Since it is a command, or an order, I would think each word should be capitalized, i.e. "Ahead Dead Slow."

Perhaps to match the "Extreme" idea, and to match the reverse, it should be "Ahead Emergency." I think that's how I'm going to do it in my SH3 setup. Of course someone has said that "Extreme" is something somebody said, and not the actual order.
