Controlling 2 servos with a keyboard press through Processing

Projects Interfacing w/ Software on the Computer
1

I am trying to move 2 servos with a keyboard press through "Processing".
I have found a very thorough run through on Instructables (http://www.instructables.com/id/Moving-a-Motor-Using-Arduino-and-Serial-Communcati/) but it doesn't recognize the key press.
The TX light flashes on the Arduino when the key is pressed, but nothing happens to the servo.
Any ideas or other pages with alternative codes?
