Hi Jeff,
You can wrap the function call that Neil mentioned in the standard $(document).ready():
<html>
<head></head>
<body>
<script src="/path/to/dpsHTMLGestureAPI.min.js"></script>
<script>
$(document).ready(function() {
adobeDPS.Gesture.disableNavigation();
});
</script>
</body>
</html>
The PDF example was showing how you can disable a particular element within the HTML (i.e. a slideshow) by passing in the element(s) into the disableNavigation() function. If you just call disabledNavigation(), as shown above, you will disable the navigation for all elements.
