Simulate :focus state on a div when key pressed
<p>I want previous and next navigation using left and right arrow keys.  I want the state of the links to change to :focus upon pressing of the arrow keys as well for tactile feedback.  Perhaps addClass could work too, but I can't figure it out.</p>

<p>Code is here:

<p>Thanks!</p>
