title: Robot Framework pressing CapsLock key
body: <p>I am using Robot Framework selenium2library to automate Chromium Embedded application.
  Requirement is to test whether the window displays a tooltip if Caps Lock key is turned on.</p>
  
  <pre><code>Press Key   #element_id   \\\20             
  </code></pre>
  
  <p>I am using above code to enable the caps lock key having 20 as ASCII code for Caps Lock key. But the above code is not working.
  The same syntax works for Enter key(ASCII value 13) and Tab Key(ASCII value 09) as shown below.</p>
  
  <pre><code>Press Key   #element_id   \\\13     
  Press Key   #element_id   \\\09     
  </code></pre>
  
  <p>Can someone please help me to achieve the Caps Lock key press using Robot Framework.</p>
