javascript: Implementing selection via click, control click and shift click, such as in windows explorer
<p>In Javascript: </p>

<p>I need to implement selection via click, control click and shift click  on rows in an html table, such as in windows explorer, and I hate to write it if the code already exists.</p>

<p>Can anyone point me in the right direction?</p>

<p>thanks!</p>
