title: How to highlight a label
body: <p>I have written my own User Defined Language in Notepad++ and all works fine but I would like to highlight all labels which are defined by all text ending with a colon, e.g.</p>
  
  <pre><code>Label1:
  GetCardNumber:
  </code></pre>
  
  <p>Is there any method of achieving this?</p>
