title: Robot Framework verify a new browser tab was opened
body: <p>For some of the web links on our page, there are external links which direct the user to say Facebook and Twitter. The links use the HMTL tag <code>target="_blank"</code> so that a new browser tab is opened for our Twitter page.</p>
  
  <p>I would like to verify 1. the new browser tab is open, 2. set focus to it and 3. validate page elements in the new browser tab. The #3 part would be easy enough, once I get focus on it. Tasks #1 and #2 though, I can't figure out, nor can I find anyone talking about this.</p>
