title: Unity KeyCode for mute button for Fire TV remote
body: <p>I have this problem when I'm looking at the amazon developer page for unity: <a href="https://developer.amazon.com/docs/fire-tv/controller-input-with-unity.html#controller-names" rel="nofollow noreferrer">https://developer.amazon.com/docs/fire-tv/controller-input-with-unity.html#controller-names</a></p>
  <p>it shows the keycodes for all the buttons, except for the mute button on the remote.
  My model is different; there's a volume button and a mute button. Neither of these are documented.</p>
  <p>Thanks for your time!</p>
