    If you want to trigger the event then it should be something like this:

    HTML

    <!DOCTYPE html>
<html>
<head>
</head>
<body>
  <input type=button value=CTRL+SHIFT+Z id=bcsz />
  <input type=button value=CTRL+Z id=bcz />
  <textarea id=t ></textarea>
</body>
</html>

    JavaScript

    var t = document.getElementById('t'), //textarea
    bcsz = document.getElementById('bcsz'), //button ctrl shift z
    bsz = document.getElementById('bcz'),  // button ctrl z
    csz = document.createEvent('KeyboardEvents'), //ctrl shift z event
    cz = document.createEvent('KeyboardEvents'); // ctrl z event

csz.initKeyboardEvent(
           'keydown', 
           true,     // key down events bubble 
           true,     // and they can be cancelled 
           document.defaultView,  // Use the default view 
           true,        // ctrl 
           false,       // alt
           true,        //shift
           false,       //meta key 
           90,          // keycode
           0
          );  
cz.initKeyboardEvent(
           'keydown', 
           true,     // key down events bubble 
           true,     // and they can be cancelled 
           document.defaultView,  // Use the default view 
           true,        // ctrl 
           false,       // alt
           false,        //shift
           false,       //meta key 
           90,          // keycode
           0
          );  

bcz.addEventListener('click', function(){
  t.dispatchEvent(cz); 
}, false);

bcsz.addEventListener('click', function(){
  t.dispatchEvent(csz); 
}, false);

    LOOK AT JSBIN LINK

    But it seems it doesn’t works. I don’t have more time to spend on this, but yeah this is kind of a security issue. I would see these docs at MSDN, W3C and MDN to see if there is a real way to do this.
