Slideshows

Hi everyone
I have five separate slideshows, all about five minutes long. I will be projecting each one consecutively (with a 30-second break between) using a digital projector and screen in a public forum. How can I change from the first slideshow’s final slide to the second slideshow’s first slide without showing my Apple Mac desktop? That is to say, how can I move from one file to another file on my laptop without showing my desktop?
I hope you can help.
