Strange things with the on() method
<p>I've run into some jQuery that has:</p>

<pre><code>  .on('mousedown.minicolors', '.minicolors-swatch', function  (event) {

       --  some code  --
   }) 
</code></pre>

<p>Control came here directly from jQuery.min.js in response to the mousedown. </p>

<p>The first question is, what is the wrapped set that the on() method is working on?
Second, the .minicolors after mousedown seems to be a "namespace," from reading the documentation.  "mousedown" is indeed the name of a plugin that has been created here.  But what, exactly, does that namespace do for us in mousedown.minicolors?</p>

<p>Thanks for adding any clarity here?</p>

<p>Thanks</p>
