title: How to click on CTRL+M (Control + M) in WebdriverIO
body: <p>I have to issue a <strong>CTRL+M</strong> action in WebdriverIO, but it is not working.</p>
  
  <p>I have tried using different ways such as: </p>
  
  <ul>
  <li><code>browser.keys('Control').keys('m');</code> </li>
  <li><code>browser.keys(['Control','KeyM', 'NULL']);</code> </li>
  <li><code>browser.keys(['Control', 'm', 'NULL']);</code></li>
  <li><code>browser.keys('Control').keys('KeyM');</code> </li>
  <li><code>browser.deviceKeyEvent(82); browser.pressKeycode(82); browser.keys('MENU');</code></li>
  </ul>
  
  <p>None of the above are working. Can anyone help me?</p>
