 CONT: When Kirk materializes in the transporter room on the  duplicate Enterprise in "The Mark of Gideon", he is standing on a  pad near the front of the chamber (near the steps). A subsequent  wide shot from within the transporter chamber, establishing there to  be no one at the transporter controls, also has Kirks transporter  pad empty. Then we return to the angle on Kirk and he is standing on  the same pad again.
