Switching between Presenter Mode and Nautilus

I am about to give a lecture where I’d need to give some examples from my Ubuntu Desktop (Terminal, Nautilus).

Is it possible to easily switch between Presenter Mode to a desktop app (say Nautilus) while connected to a projector via HDMI?

I have to go back and forth between Impress and the desktop apps…

Every time I exit the presenter mode and go back (F5) the presentation starts over…

Thanks!
