	<h3>Accessibility jQuery tabindex enter/return key "clickable" fix</h3>
	<p>Often UI elements with tabindex="0" will not respond to hitting the enter key. The easiest way to fix this is to create a simple keypress event that simulates a keypress. This hack doesn't require a fix to existing libraries. Below is jQuery Cycle 2 slide show with a pager that normally does not respond to the return key.</p>
	<div class="cycle-slideshow"  data-cycle-timeout="0" data-cycle-prev="#prev" data-cycle-next="#next" data-cycle-pager-template="<span tabindex='0'>•</span>">
		 <div class="cycle-pager"></div>

	</div>

	<a href=# id="prev" tabindex="0"><i class="fa fa-chevron-left" aria-hidden="true"></i>
 </a> 
	<a href=# id="next" tabindex="0"><i class="fa fa-chevron-right" aria-hidden="true"></i>
</a>
	<div class="cycle-pager"></div>
	<p>Note that the chevrons do not require any additional JS for the browser to trigger when focused on (tabbed to) and pressing the the enter key. A tags with a href value automatically work with most browsers. However, the spans in this example are purposely not a tags with href values to demostrate the returnKepyress script.</p>
