title: On key press of Enter, click a button in vuejs
body: <p>Here is my fiddle: <a href="https://jsfiddle.net/inchrvndr/52a7ppt2/" rel="noreferrer">DEMO</a></p>
  
  <p>There is a button called "fb-send", which has to get clicked on key press on "enter" in the input field. How to achieve this?</p>
  
  <pre><code>&lt;input @keyup.enter="" placeholder="Reply here" class="fb-comment-input" /&gt;
  &lt;i class="material-icons fb-button-right fb-send"&gt;&amp;#x21E8;&lt;/i&gt;
  </code></pre>
  
  <p>Any help would be much appreciated. Thank you.</p>
