title: Is it possible to simulate pressing 'Down' arrow?
body: <p>I try to figure out how to send <kbd>Down</kbd> in <a href="/questions/tagged/puppeteer" class="post-tag" title="show questions tagged &#39;puppeteer&#39;" rel="tag">puppeteer</a>, I tried with the int code <code>40</code> or <code>Down</code> string, but none works.</p>
  
  <p>Is there a proper way ? Can't figure it out after reading <code>~/node_modules/puppeteer/lib/Input.js</code></p>
  
  <pre><code>const elementHandle = await page.$('selector');
  await elementHandle.type('something');
  await page.keyboard.press(40); // fail
  </code></pre>
