Tabulator-Key

Hi,

How can I use the Tab key in FCKEdior?

I found the script by Tab key in text Area, unfortunately, I can not integrate this.

<script type="text/javascript">
<!--

function insertTab(event,obj)
{
   var tabKeyCode = 9;

   if(event.which) // mozilla
      var keycode = event.which;
   else // ie
      var keycode = event.keyCode;

   if(keycode == tabKeyCode)
   {
      if(event.type == "keydown")
      {
         if(obj.setSelectionRange)
         {
            // mozilla
            var s = obj.selectionStart;
            var e = obj.selectionEnd;
            obj.value = obj.value.substring(0, s) + 
               "\t" + obj.value.substr(e);
            obj.setSelectionRange(s + 1, s + 1);
            obj.focus();
         }
         else if(obj.createTextRange)
         {
            // ie
            document.selection.createRange().text="\t"
            obj.onblur = function() { this.focus(); this.onblur = null; };
         }
      }

      if (event.returnValue) // ie ?
         event.returnValue = false;

      if (event.preventDefault) // dom
         event.preventDefault();

      return false; // should work in all browsers
   }

   return true;
}
