How to detect shift down when clicking on ScriptUI button?

问题

On my scriptUI panel, I have a button. How can I detect whether the user is holding the shift key when they click on the button?

You can add an eventListener to your button.

var win = new Window ("dialog");
win.aButton = win.add ("button", undefined, "Button");
win.aButton.addEventListener ("click", function (k) {
      if (k.shiftKey) {
        alert("foo");
      }else{
        alert("bah");
      }
  });
win.show ();
