title: Tabbing between NSTextFields with nextKeyView
body: <p>I have a single NSViewController with the following layout, set using a storyboard:
  <a href="https://i.stack.imgur.com/Xus0B.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Xus0B.png" alt=""></a></p>
  
  <p>The nextKeyView outlet of each of the NSTextFields is configured to be the next NSTextField in the order presented on the screenshot. For example, I chose the server NSTextField in IB and dragged from the nextKeyView outlet in Connectivity inspector to the login NSTextField, and did the same for the rest of the fields.</p>
  
  <p>When the app is launched, any tab press on any of the field moves the selection to the first NSTextField. How do I achieve the desired tabbing between the fields?</p>
  
  <p>I tried this in the respective WindowController, but to no avail:</p>
  
  <pre><code>- (void)windowDidLoad {
      [super windowDidLoad];
  
      self.window.initialFirstResponder = self.serverTextField;
  }
  </code></pre>
