title: Listening to "esc" key event on div component in Vue.js
body: <p>I wish to listen to an 'esc' key event in order to call a method in a Vue component.
  The docs shows this example:</p>
  
  <pre><code>&lt;input v-on:keyup.enter="submit"&gt;
  </code></pre>
  
  <p>but i'm using a <code>&lt;div&gt;&lt;/div&gt;</code>, and need to catch the event from outside.
  However, I wish NOT to overload global handlers or anything like that.</p>
  
  <p>Any suggestions?</p>
