Hello Anita, thanks a lot for this detailed and understandable answer:-)
I have two problems. In B point 2 I only have on Enter or on Exit. Furthermore (when I chose on Enter) in point 7 there is no cpInfoCurrentFrame but only cpInfoCurrentSlide or rdInfoCurrentFrame. So When I select either of them when I use the button it directs me to the previous slide but not to the beginning of the current one...Do you know what I might have to do?
