title: Changing navigation title programmatically
body: <p>I have a navigation bar with a title.
  When I double click the text to rename it, it actually says it's a navigation item, so it might be that.</p>
  
  <p>I'm trying to change the text using code, like:</p>
  
  <pre><code>declare navigation bar as navagationbar here
  button stuff {
      navigationbar.text = "title"
  }
  </code></pre>
  
  <p>That's not my code obviously, just showing how it would work.</p>
  
  <p>So whenever I press the button, I want the title to change.</p>
