How this works

If you are curious about how this works, then below is the actual code behind the widget. The code listens for Keyboard inputs and if detects an Arrow Key event, it will redirect the user to the newer or older page. The code picks the newer and older page links from the Blogger’s Page Navigation Links.

<script type='text/javascript'>
document.onkeyup = function(event)
{
if (document.activeElement.nodeName == 'TEXTAREA' || document.activeElement.nodeName == 'INPUT') return;
event = event || window.event;
switch(event.keyCode)
{
case 37:
var newerLink = document.getElementById('Blog1_blog-pager-newer-link');
if(newerLink !=null) window.location.href = newerLink.href;
break;
case 39:
var olderLink = document.getElementById('Blog1_blog-pager-older-link');
if(olderLink!=null) window.location.href = olderLink.href;
}
};
</script>
