Bind an event handers to allow a click or return key to activate the callback.
This is good for accessibility since a return on the keyboard will have the
same effect as a click, if the element has focus.
 @param {element} n Element to bind the action to
 @param {object|string} selector Selector (for delegated events) or data object
  to pass to the triggered function
 @param {function} fn Callback function for when the event is triggered
