1. With your projector operating in Extended Desktop mode, your presentation and the contents of your MBP screen are completely separate. You can do anything you like on the MBP's screen and your audience will see none of it. No need to toggle anything during the presentation.
2. I don't understand your second question, because "the whole screen on the LCD projector screen will go black "W" and it will turn white" makes no sense.
