                are triggered.  This is typically used when going back one
                effect leads to the previous slide.  On that slide all
                effects have to be shown in order to continue the backward
                travelling.
                When <FALSE/>, the default, then no main sequence effect is
                triggered.
                </li>
            <li>name: SkipSlideTransition, value: boolean.
                When <TRUE/> then the slide transition animation, if there
                is any, is not displayed.  This is typically used when going
                back one effect leads to the previous slide.  Typically used
                together with SkipAllMainSequenceEffects also being <TRUE/>.
                When <FALSE/>, the default, then the slide transition
                effect, if it exists, is played.
