title: List of key codes (InputProcessor)
body: <p>Interface <code>InputProcessor</code> implements the <code>keyUp</code> and <code>keyDown</code> methods that pass key-codes in <code>int</code>. Where can I find a list of these codes corresponding to keyboard input?</p>
  
  <pre><code>public boolean keyDown(int keycode) {
          return false;
      }
  
  public boolean keyUp(int keycode) {
          return false;
      }
  </code></pre>
  
  <p>Let's say i want to map <code>UP</code> to a event. How do I know the keycode of <code>UP</code>?</p>
