Hi Pat,
In order to navigate to a chosen slide in your presentation while in Presenter View, you can add an object that you can click to go to that slide. For example, you add a picture then add an action to this(eg. go to a certain slide). Once you're in Presenter View and click this, it will take you to the slide you linked to it. You may follow the steps provided in this article to do so.
Feel free to post back should you need further assistance.
