Selecting range of items in unordered list 
<p>I want to allow user to select range of items in my unordered list by allowing him to press cntrl key and then select first &amp; last item, all items in between would be selected.
I'm using JQuery, Any suggestion how to approach this problem?
Here is html:</p>

<pre><code>  &lt;ul id="ulList_1"&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 1&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 2&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 3&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 4&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 5&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 6&lt;/a&gt;
     &lt;/li&gt;
     &lt;li&gt;
        &lt;a href="#"&gt;item 7&lt;/a&gt;
     &lt;/li&gt;
  &lt;/ul&gt;
</code></pre>

<p>So if user press cntrl key and select "item 2" and then select "item 6" I want all items between "items 3,4,5" to be selected as well.
Thanks</p>
