+You can also bind event listeners to elements:

+```javascript
+var click = function() {

+};
+
+rect.on('click', click);
+```
+
+Note that the context of event listeners is not the same as events, which are applied directly to the element. Therefore `this` will not refer to the element when using event listeners.

+Unbinding events is just as easy:
+
+```javascript
+rect.off('click', click);
+```
+
+But there is more to event listeners. You can bind events to html elements as well:
+
+```javascript
+SVG.on(window, 'click', click);
+```
+
+Obviously unbinding is practically the same:
+
+```javascript
+SVG.off(window, 'click', click);
+```
+
 Available events are `click`, `dblclick`, `mousedown`, `mouseup`, `mouseover`, `mouseout`, `mousemove`, `touchstart`, `touchend`, `touchmove` and `touchcancel`.
