If you want to access slides from outside the plugin, e.g. a certain link / button should display a certain slide, you can help yourself as follows:
1. first create a corresponding link, including class.
<a href="#" class="slider-link">Show Slide Number Two</a>
2. the following code is placed in the Custom JavaScript section of the slider itself.
jQuery('body').on('click', '.slider-link', function() { // revapi5 equals the API identified for the slider // revshowslide(2) will load the second slide revapi5.revshowslide(2); return false; });
