I can't for the life of me figure out how to change between slides!

I have 2 slides, and I have the cloud template.
Could someone explain how exactly I can move between slides?

I have buttons that were included in the template, do I use actions to change between slides or just double click on button?

Please I really need help

The buttons Next and Previous Slide added via the Navigation Object Library should do the job. Add them to the master slide to access them on all slies.

If you want to change to the next *frame* you need to add a button and assign the corresponding "GOTO" action
