In the action buttons choice on the auto shapes tool on the drawing toolbar. You will find the Hyperlink options, with an arrow to indicate there are more options. Click on Hyperlink now and then on the home button

I have set the Home button to link to the first page of my Presentation. To do this: Add a custom picture, you will have to draw the shape but it is automatic. A menu box will
appear where you can choose to hyperlink to the first page. When you are showing your presentation on the screen you will be able to click on the Home button to return to the beginning of your presentation.

To SET the Action of the hyperlink, ie on mouse click or mouse over, first ensure that the object has the selection handles around it. (the white squares) if not, click on the object/home icon then right click on the mouse and choose hyperlink/edit hyperlink.
