Guess which switch controls the projector screen?

(picture of projector screen) This picture shows a projector screen in a conference room. The white screen is lowered from the ceiling in front of a blackboard. To the right of the screen are some electrical switches. Guess which switch raises and lowers the screen? The switch next to the screen? No, it's the switch farthest away from the screen!

Design suggestion

Place a control next to the device it controls.
