title: Comment/Uncomment multiple lines in JupyterNotebook hotkey
body: <p>I was wondering, if there is a PRO way of commenting/removing multiline # comments in JupyterNotebooks.</p>
  <pre><code># line1
  # line2
  # line3
  </code></pre>
  <p>Something like <strong>SHIFT + &quot;</strong> for adding triple quotes.</p>
