How do I know whether the command/apple key is pressed
<p>In my JQuery code, I have something like:</p>

<pre><code>onKeyDown(event)
{
    if (event.ctrlKey) ...
}
</code></pre>

<p>However, on a Mac, I want to know whether the command/key (not control) key is pressed.</p>

<p>What's the best way to do this?</p>
