title: How to keep the focus on a canvas always?
body: <p>I've been looking for a solution in this forum, but not found yet. I need to keep the focus on a canvas element always, no matter where i click on the page. I have several buttons, and inside each onclick event i write:</p>
  
  <pre><code>document.getElementById('canvas').focus();
  </code></pre>
  
  <p>This does the trick, but i think is not the best practise. Any idea?</p>
