Sound error is played when $(document).keydown is called using ALT + Some Key. [?]
<pre><code>$(document).keydown(function(e){
    if(e.altKey &amp;&amp; e.keyCode == 77){
       document.title = 'Something';
       return false;
    }
});
</code></pre>

<p>The function is pretty simple, it's an event listener to get when the User press ALT M, then do something.
But this code is playing a sound error when we hit ALT M, yes it changes the title as expected, but it also plays a sound error. (I'm testing on Windows 7 in Google Chrome)</p>

<p>What should I do to make it not play this error?</p>
