Begin a speed walk in script????

is there any command that send the following ("4n3esuwdLW") to script and then react as speed walking???

i have read the help file, it just tell me to do the following

1.EvaluateSpeedwalk (Evaluates a speed walk string)
2.ReverseSpeedwalk (Reverses a speed walk string)
3.SpeedWalkDelay (The number of milliseconds delay between speed walk commands)

in these examples, they just show how to make make them as note on output screen...

What are you trying to do?
Just send them to the speedwalk queue via scripting?

Try the Queue command:
