re (It works for me)
I think this is what you sent as morse code, though the spacing was difficult. If I recieved it at 5wpm I could have understood more.

Besides sending morse code by using one key for your dits and dahs, how else would you communicate using alphanumeric keys? This would be applicable if you had a phone but no voice Ie your face got smashed on the driving wheel.

As to your logical answers. Very Good answers.
