title: Mapping arrow keys to scrollwheel function?
body: <p>I am running a slideshow on a client site.  The slideshow animates each slide, and relies SOLELY on the scrollwheel of the mouse although it also 'swipes' when in touchscreen devices.</p>
  
  <p>It's important to note here that the page doesn't <em>actually</em> scoll when using the scrollwheel, it only activates the next slide animation.  The webpage never actually scolls in the traditional sense...</p>
  
  <p>However some people don't use a scrollwheel, they use keyboard arrows. </p>
  
  <p>Is there a way, ideally using JavaScript, to force the arrow keys to emulate a single scroll of the mousewheel?</p>
  
  <p>I apologise for lack of code or previous efforts - I haven't been able to find anything with regards to this problem and the code is well embedded in the Slideshow extension.  I'm hoping to add my own JS to complement the base Slideshow.</p>
