title: What is the Android Studio keyboard shortcut for Package Explorer?
body: <p>I've tried googling, and so far the closest answer is this one:
  <a href="https://groups.google.com/forum/#!topic/android-developers/U7yU2mz5L0c" rel="noreferrer">Android Studio is driving me nuts</a></p>
  
  <p>However, it's not really a keyboard shortcut, and besides, the "Project Pane" isn't always visible. (If anyone knows how to make it permanently visible, please tell me.)</p>
  
  <p>What I do is search "Project" on the quick search bar, click on it to make it appear, and then switch to Package Explorer.</p>
