Managing Kernels and Terminals
------------------------------

The Running tab in the left sidebar shows a list of all the kernels and
terminals currently running across all notebooks, code consoles, and
directories:

   :align: center
   :class: jp-screenshot

As with the classic Jupyter Notebook, when you close a notebook
document, code console, or terminal, the underlying kernel or terminal
running on the server continues to run. This allows you to perform
long-running actions and return later. The Running tab allows you to
re-open or focus the document linked to a given kernel or terminal:

Kernels or terminals can be shut down from the Running tab:
