@whatnao You could also run the projector in an activated scene with a keyboard watcher that listens for a trigger and toggles the projector on or off - so the movie keeps running and the projector is what goes on or off. Since the scene is active the keyboard watcher will react even if you are currently in another scene.

i ve saw you have an answer but because , one question has often many answer , I would know if it could possible to use user actor ? 

Build your user actor as you builded your first scene , then past that user actor in each scene that you need it . Then each time you need ( new show ?)  Change the value in the user actor in the first scene and when close the user actor , select update all . 

It will work , no ?

Thank you Michel for the fast answer.

This seems to work for what I need.

@mclefferson

You are correct. It appears some inputs are no longer available.
I have logged a ticket, to have this inconsistency looked into.
thank-you for the feedback.
