86<li><b>delay</b> : Number<p class="sub-desc">The number of milliseconds to delay the invocation of the handler after the event fires.</p></li>

90handler is <em>not</em> invoked, but the new handler is scheduled in its place.</p></li>
91</ul><br>
92<p>
93<b>Combining Options</b><br>
94Using the options argument, it is possible to combine different types of listeners:<br>
95<br>
96A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
97<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
98    single: true,
99    delay: 100,
100    forumId: 4
101});</code></pre>
102<p>
103<b>Attaching multiple handlers in 1 call</b><br>
104The method also allows for a single argument to be passed which is a config object containing properties
105which specify multiple handlers.
106<p>
107<pre><code>foo.on({
108    <em>'click'</em> : {
109        fn: <b>this</b>.onClick,
110        scope: <b>this</b>,
111        delay: 100
112    },
113    <em>'mouseover'</em> : {
114        fn: <b>this</b>.onMouseOver,
115        scope: <b>this</b>
116    },
117    <em>'mouseout'</em> : {
118        fn: <b>this</b>.onMouseOut,
119        scope: <b>this</b>
120    }
121});</code></pre>
122<p>
123Or a shorthand syntax:<br>
124<pre><code>foo.on({
125    <em>'click'</em> : <b>this</b>.onClick,
126    <em>'mouseover'</em> : <b>this</b>.onMouseOver,
