+## Limit frequency
+
+You must use .mouseweel() method instead of .on() method to add the delay parameter. It will limit the frequency of triggered events.
+
+```js
+    // Exemple : 250 milliseconds = 4 times / second
+    $('selector').mousewheel(function(event, delta, deltaX, deltaY) {
+    	console.log(delta, deltaX, deltaY);
+	}, 250);
+```
