Replacing selected text in the textarea
<p>what is the best way to do this in jQuery? This should be a fairly common use case.</p>

<ol>
<li>User selects text in a textarea </li>
<li>He clicks on a link </li>
<li>The text in the link replaces the selected text in the textarea</li>
</ol>

<p>Any code will be much appreciated - I am having some issues with part 3. </p>
