title: Jupyter lab shortcuts
body: <p>I've been using Jupyter Notebooks for a couple of years now. I've just headed over to Jupyter Lab, but I've found the lack of shortcuts to be a burden.</p>
  
  <p>For example, I noticed that I can search for commands in the left hand palette. <strong>But I can't seem to easily bind them to a keyboard shortcut. Is this even possible?</strong></p>
  
  <p>For example, I want to collapse the current cell output with "O" and collapse all code cells with "Shift O".</p>
