Keynote - Make main screen Freeze while editing slides

[matthewlesh]

I'm just wondering would it be possible in Keynote to freeze the main screen (where the presentation is being shown) while allowing me on the other screen to go change what a slide says and play around with text, or even swap to a video..??

Any help would be great... thanks.

I just have to bump this... There MUST be some way to do it...??
