title: dat.gui how to hide menu with code
body: <p>I made a menu using dat.gui for my applcation with Three.js.
  It works fine, I have also discovered that pressing h key I can hide the menu created with dat.gui.
  My question is how can I make the menu appear/disappear directly from the code?</p>
  
  <pre><code> var gui = new dat.GUI();
   gui.add(text, 'message');
   gui.add(text, 'speed', -5, 5);
  
   gui.???
  </code></pre>
  
  <p>I tried to use the property of the DOMElement hide and it works but I would like a unique way to handle this function.
  There is a function to call? I have noticed that JavaScript events related to the keystrokes are related to the scope via a bind in the library.
  But what is the correct way to do this?</p>
