  var selected_text;
  if(window.getSelection){
   selected_text = window.getSelection().toString();
   if(!(selected_text.length > 0)){
    var start = o.selectionStart;
    var end = o.selectionEnd;
    selected_text = o.value.substr(start,end-start);
   }
  }
  else if(document.getSelection){
   selected_text = document.getSelection();
  }
  else if(document.selection){
   selected_text = document.selection.createRange().text;
  }
  selected_text = selected_text.replace(//x0D/x0A|/x0D|/x0A/g,' ')
