You should use Pronto Edit software and open a default project. At the bottom it says 'building blocks' , there you should find tabs for example 1/2 and 2/2. You can copy it into you own project and add it. If you did, you right click on the tab and click on 'ungroup', now the 1 and 2 split. (If the 1 and 2 arent split already) If you are in the first page and want to make a link to the second, you should click on the 2, go to action and add a page jump the second page. On the second page you use the tab image 2/2 and there you can make a link to the first page again. I hope you understand, you can just tell me, and I will explain again.
