If you'd like to make scrolling with the mousewheel navigate a flipbook or a slider document, add the following code in the JavaScript portion of the Resources section of the Export HTML5 with in5 dialog:
$(window).on('wheel', function(event){ if(event.originalEvent.deltaY !== 0){ (event.originalEvent.deltaY < 0) ? nav.back() : nav.next(); } });
Note: this code is provided as is, but may required tweaking if you want custom behavior (e.g., to only navigate through one page while the mousewheel is scrolling).
