title: Open a blank window, write to it, and select the written text
body: <p>I'm trying to open a blank window with Javascript, write text to it, and then select the text that I wrote, all automatically.</p>
  
  <p>I have:</p>
  
  <pre><code>var myWindow=window.open('');
  myWindow.document.write("hey");
  myWindow.select();
  </code></pre>
  
  <p>which opens the window and writes the text, but does not select it.</p>
