title: How to make the gdb tui window bigger
body: <p>I am debugging my application by using <code>gdb</code> in <code>tui</code> mode.</p>
  
  <p>When I start my debugging session the main windows is split in 2 equal-sized parts.</p>
  
  <ul>
  <li>the window with the source code (upper side)</li>
  <li>the window where I can call gdb commands (lower side)</li>
  </ul>
  
  <p>The 2 windows are the same exact size.</p>
  
  <p>Is there any way or key combination to make the source code window bigger than the other ones? Anything to make it larger?</p>
