title: Continuous onkeydown event in Firefox
body: <p>I have a regular onkeydown event handler that fires a function, like this:</p>
  
  <pre><code>window.onkeydown = onKeyDown;
  </code></pre>
  
  <p>It essentially works, but it only captures 1 key in Firefox. Then I have to release it and press again.</p>
  
  <p>Google chrome offers me a continuous grab, so I wonder if this is by choice.</p>
