Greetings!

My projector requires two commands to be turned off:
1) pressing the "on/off" button brings up a confirmation dialog, asking for
2) the "on/off" button to be pressed once more to turn the projector off.

Is there a way to turn off the VP in only one push of the on/off button, 
eliminating the confirmation dialog and second push?
Thanks for your advice! :-)
