title: How to simulate a key-press in ExtendScript?
body: <p>currently I want to write a script for AE, which relieves me of some keyboard inputs.
  Once the script is running, I want to click with the mouse, and then some key-inputs for example X Y and Z should be simulated. The little GUI and the eventhandler are no problems, but the simulation of key pressing. Please help.</p>
  
  <pre><code>var win = new Window ("dialog", "Dummy");
  win.aButton = win.add ("button", undefined, "Start");
  win.bButton = win.add ("button", undefined, "Stop");
  
  //Start
  win.aButton.onClick = function (event){
  var activeViewer = app.activeViewer;
      if activeViewer.type == ViewerType.VIEWER_COMPOSITION){
  
       HERE SHOULD THE KEYS x, y AND z PRESSED VIA THE SCRIPT 
  
      }else return;
  }
  //Stop
  win.bButton.onClick = function (event){
      win.close();
      return;
  }
  win.show();
  </code></pre>
