-<div class="warning">Note: This method signature was removed in jQuery 1.9. jQuery also provides an animation method named .toggle() that toggles the visibility of elements.</div>

-The [`.toggle()`](http://api.jquery.com/toggle-event/) method is triggered by the "click" event and accepts two or
-more functions. Each time the click event occurs, the next function in the
-list is called. Generally, `.toggle()` is used with just two functions;
-however, it will accept an unlimited number of functions. Be careful, though:
-providing a long list of functions can be difficult to debug.

-}, function() {
