title: How to press a key using nodejs?
body: <p>I would like to know how to get a certain key on the keyboard to be pressed via code on nodejs.</p>
  
  <p>For instance, I want the f3 button to pressed once the following page is rendered:</p>
  
  <pre><code>var express = require('express');
  var router = express.Router();
  
  
  /* GET home page. */
  router.get('/', function(req, res, next) {
     // press key
  });
  
  module.exports = router;
  </code></pre>
