Windows Web app JupyterLab default shortcuts

Practice this

To close the current tab in JupyterLab, press Alt + W. It is listed for Windows, and no Mac version is documented here. It works in the browser version.

Where it works: Workspace

The files do not name the Mac key for Alt, so no Mac keys are shown.
