title: pyautogui: press two keys at the same time
body: <p>I am using <code>pyautogui</code> to simulate pressing shift and end at the same time - when I type this myself, it highlights all the entries, however when I do it via the code below, it just moves to the end file - not highlighting every component, so it seems like shift isn't being pressed. Was wondering if anyone had any ideas?</p>
  
  <pre><code>pyautogui.keyDown('shift')
  pyautogui.keyDown('end')
  pyautogui.keyUp('end')
  pyautogui.keyUp('shift')
  </code></pre>
