Replicating functionality of stackoverflow's tag system
<p>On stackoverflow, while in the Tag-inputbox if you hold the left key button, it will go all the way to the left and open every tag for editing, same goes for the right key, and the backspace.
<br>I am trying to replicate the same functionality on mine.</p>

<p>I have the following code: <a href="http://jsfiddle.net/hAKMN/" rel="nofollow">JSFiddle</a></p>

<p>The problem with the current code is that I am not sure how to implement the arrow keys movements.</p>

<p>Any ideas?</p>
