title: Flex/Air : Text Area with Line Number Filtering
body: <p>I need to have a Text Area With Line Numbers,
  &amp; once the Text File is Imported to the Text Area..
  the user must be able to select the line numbers &amp; see the filtered output.</p>
  
  <p>I have implemented the same with Numeric steppers.
  I am in search of an enhanced component.</p>
  
  <p>are there better Advanced Components for Textarea ?
  Any Advanced Textarea component with built-in Search/Replace/Filter Capabilities ?</p>
  
  <p>Cheers,
  Ajay</p>
