Navigation inside SlideShow layouts
A slide show can present its slides in a complete celements layout (TODO link to SlideShow layouts docu). Cells of any Cell-Type can be used inside a SlideShow layout. This means that too a Navigation Cell can be included inside a SlideShow layout. Moreover you can have links inside slides connecting to an other slide.
Now the question arises: What do you expect to happen if the user clicks on such an internal link (in a Navigation-Cell or in Text)?
This you can influence directly with css classes. To make the SlideShow automatically loads the linked slide and thus preventing the browser from navigating to the slide give a surrounding element the celPresSlideShow_navigation css class. The slide show then will automatically connect to links leading to an other slide.
