title: Pressing Enter button in puppeteer
body: <p>Pressing enter in puppeteer doesn't seem to have any effect. However, when I press other keys, it does what it should. 
  This works:</p>
  
  <pre><code>await page.press('ArrowLeft');
  </code></pre>
  
  <p>This doesn't:</p>
  
  <pre><code>await page.press('Enter');
  </code></pre>
  
  <p>This is how the input looks like:</p>

  <p>Any ideas?</p>
  
  <p>EDIT: I've also tried page.keyboard.down &amp; page.keyboard.up to be sure.</p>
