+
+    NOTE: Generally, the `on()` method should be avoided on `NodeLists`, in
+    favor of using event delegation from a parent Node.  See the Event user
+    guide for details.
+
+    Most DOM events are associated with a preventable default behavior, such as
+    link clicks navigating to a new page.  Callbacks are passed a
+    `DOMEventFacade` object as their first argument (usually called `e`) that
+    can be used to prevent this default behavior with `e.preventDefault()`. See
+    the `DOMEventFacade` API for all available properties and methods on the
+    object.
+
+    By default, the `this` object will be the `NodeList` that the subscription
+    came from, <em>not the `Node` that received the event</em>.  Use
+    `e.currentTarget` to refer to the `Node`.
+
+    Returning `false` from a callback is supported as an alternative to calling
+    `e.preventDefault(); e.stopPropagation();`.  However, it is recommended to
+    use the event methods.
+
+    @example
+
+        Y.all(".sku").on("keydown", function (e) {
+            if (e.keyCode === 13) {
+                e.preventDefault();
+
+                // Use e.currentTarget to refer to the individual Node
+                var item = Y.MyApp.searchInventory( e.currentTarget.get('value') );

+Subscribe a callback function to execute in response to a DOM event or custom
+event.
+
+Most DOM events are associated with a preventable default behavior such as
+link clicks navigating to a new page.  Callbacks are passed a `DOMEventFacade`
+object as their first argument (usually called `e`) that can be used to
+prevent this default behavior with `e.preventDefault()`. See the
+`DOMEventFacade` API for all available properties and methods on the object.
+
+If the event name passed as the first parameter is not a whitelisted DOM event,
+it will be treated as a custom event subscriptions, allowing
+`node.fire('customEventName')` later in the code.  Refer to the Event user guide
+for the full DOM event whitelist.
+
+By default, the `this` object in the callback will refer to the subscribed
+`Node`.
+
+Returning `false` from a callback is supported as an alternative to calling
+`e.preventDefault(); e.stopPropagation();`.  However, it is recommended to use
+the event methods.
+
+@example
+
+    Y.one("#my-form").on("submit", function (e) {
+        e.preventDefault();
+
+        // proceed with ajax form submission instead...
+    });
+
+@method on
+@param {String} type The name of the event
+@param {Function} fn The callback to execute in response to the event
+@param {Object} [context] Override `this` object in callback
+@param {Any} [arg*] 0..n additional arguments to supply to the subscriber
+@return {EventHandle} A subscription handle capable of detaching that
+                      subscription
