Hi, If you want to jump from say, slide 6 to slide 3, all you have to do is go to the 'slideshow' menu, 'Action Buttons', and then 'Action Button: Custom'. From there you can change when you want it to change, (eg. on mouse click) and which slide you want it to jump to. You can also do other functions from that as well.

Hope this is useful
