title: How to replace uppercase letters to lowercase letters using regex in Eclipse?
body: <p>I'd like to go through all of my source code files and replace every occurence of <code>k_Xyyy</code> with <code>k_xyyy</code> (switch the first letter after <code>k_</code> from uppercase to lowercase).</p>
  
  <p>I'm using the eclipse dialog to search and replace multiple files. Right now I have the regex <code>\bk_([A-Z])</code>.</p>
  
  <p>How do I specify the replacement string of the regex?</p>
