title: Force regex to be case sensitive?
body: <p>Suddenly my notepad++ regex search became case insensitive. Which is highly problematic to me.</p>
  
  <p>It's the first time I notice this, I searched the internet but the only topics I find are to turn regex case insensitive.</p>
  
  <p>Is there any way to force them to be case sensitive ?</p>
  
  <p>Thanks</p>
