Thanks Lieve. I will check this.
It is pretty easy, didn't want to repeat what was written out there: have a shape button on the main master slide, doesn't need any command but it can pause each slide at its last frame.
You have to be aware of the fact that slides in an eLearning course shouldn't be treated the same way as in a presentation. In Captivate often content is spread over several slides for other reasons and in that case having the automatic transition to the next slide is really wanted.
