From Operation : Annihilate....Eddie Paskey pushes the three sliding controls up to send Kirk and friends down to Deneva. From Omega Glory.,.Frank Vinci pulls the sliders down to send Kirk and buddies over to the Exeter. (Actually Frank pulls the middle one down as Kirk enters the Transporter Room. Then he pulls the 2 outside sliders down to activate the Transporter beams) I’m sure someone on TrekBBS can explain this mystery. I always thought you pushed up to beam down and pulled down to beam down.
