Question

Which are ways action buttons can be used in presentations?

Answer 1

You could Do Ctrl + F5 to present your google slides

You could Animate Objects/Units by one of the drop down menus in google slides

You could add a link by copying the link you want to put in by highlighting the link, pressing Ctrl + C (to copy) and Find where you would like to place it and press Ctrl + V
(To Paste)

If you press on a google slide and do not do anything else, at the top it should say theme Or background, there you could select a image from your device or a solid color or Gradient of a color for your background.
