title: Block indent jupyter notebook
body: <p>Does anyone know how to get a command shortcut to work for block indenting and un-indenting in Jupyter notebooks?
   
  In the Jupiter notebook command group there is a command “automatically indent selection”. When I put in a command mode control-/  for that command the notebook does block commenting. 
   
   
  I don’t see any other command that refers to indenting.
   
  I can’t seem to figure this </p>
