Great idea Jim, although, I did so want to make use of the dragSpeed thing to have precise control of the trace. Turtle Graphics will provide a great compromise!

Thanks, Roger

Actually you can set the "linesize" of the line or polygon tool; you
can have both your arrow and line size.

What you need apparently is more intermediate points in order to
control rate of drawing between end points. One way to do this would
be with, you guessed it, Turtle Graphics. (You would want the version
that does vector graphics, not bit map.) For example, you could
control the motion between any two points A and B as follows:

on mouseUP
   put 0,0 into A
   put 300,300 into B
   startTurtle
   setXY A
   setheading direction(B)
   put distance(B) into d
   put 3 into s --Or whatever works for you
   repeat round(d/s) times
     forward s
     --Perhaps a "wait" here
   end repeat
   setxy B --Just to take care of the rounding error
end mouseUP

And you could iterate this to take you through a sequence of points.

Jim
