title: React history.push allow user to open in new tab
body: <p>Navigation between pages in my navbar is done using an onClick handler, rather than through hrefs. When doing this, I can't either middle click to open in a new tab or right click on the link and select open in new tab. I am using react-router-v4.</p>
  
  <p>An example of a route.</p>
  
  <pre><code>&lt;a onClick={() =&gt; this.props.history.push('/conference/')}&gt;Conference&lt;/a&gt;
  </code></pre>
  
  <p>Is there a way to allow this to happen in react or should I be using hrefs instead?</p>
