I'm using Universal Analytics tracking code and would like to start tracking click events for one of the buttons. I added the ga('send'...) on click event via jQuery. Do I need to make any changes to the actual Universal Analytics tracking snippet?

No, you don't need to make any changes. I'm assuming you are invoking the library and creating the tracker through the standard method.Your code should look something like this:<button onclick=ga('send', 'event', 'your_category', 'your_action', 'your_label');>With jQuery, placing an event listener on the button:$('button').click(function(){    console.log(sending your event); // use this to debug    ga('send', 'event', 'your_category', 'your_action', 'your_label');}
