I just looked up that scene on YouTube, and there&#x27;s the switcher. Thanks for the chuckle.<p>At least on the Grass Vally switchers, I think you just had to press the star from the group of black and white wipe effect buttons in the upper right, the press &quot;wipe&quot; next to the program fader. You could use the little black joystick in the upper right corner to make the effect move.<p>At least so I remember from being eight.
