title: triggerHandler vs. trigger in jQuery
body: <p>Out of curiosity -- what is the purpose of / use cases for jQuery's <code>triggerHandler</code>? As far as I can tell, the only "real" differences between <code>trigger</code> and <code>triggerHandler</code> is whether or not the native event fires, and event bubbling behavior (though <code>triggerHandler</code>'s bubbling behavior doesn't seem hard to replicate with <code>trigger</code> in a few more lines of code).  What is the advantage to ensuring the native event does not fire?</p>
  
  <p>I'm curious if this is a convenience function or there's a deeper reason it exists, and what why/when I would use it.</p>
