title: What is the shortcut key to comment multiple lines using PyCharm IDE?
body: <p>In Corey Schafer's <em><a href="https://youtu.be/5qQQ3yzbKp8" rel="nofollow noreferrer">Programming Terms: Mutable vs Immutable</a></em>, at <a href="https://youtu.be/5qQQ3yzbKp8?t=186" rel="nofollow noreferrer">3:06</a>, he selected multiple lines and commented them out in PyCharm all in one action.</p>
  <p>What is this action? Is it a built-in shortcut in PyCharm that I can use or configure myself?</p>
