Switch to the Mouse tab.
If you wish the slide show to react to a mouse click, select:
1. "Go to address", you should also indicate the URL and the window opening mode (blank, self, parent, top). If you wish to attach an individual URL to each slide you should use the (*) symbols set where (*) is the sequence number of the image. E.g.: http://www.yoursite.com/index.php?page=(*)
2. "Next Frame" - switch to the next frame. In this case transition will be performed after pressing the "Space" button on the keybord.
3. "Stop / Next Frame" - stop / switch to the next frame.
