Timi Oshin has updates on SSMS and Azure Data Studio:
Azure Data Studio 1.35 now supports easier keyboard navigation in notebooks without mouse clicking. This is done by hitting the Esc key and navigating between cell rows using the Up and Down arrow keys. To enter edit mode, hit the Enter key on the keyboard. The new Table Designer preview feature supports creating new tables and editing existing tables on a connected SQL Server instance. This is a highly requested product enhancement and enables more productive schema management with a modern, streamlined UX.
Haha! It only took several years but my hectoring finally pays off. Now for the full set of Jupyter keyboard shortcuts…
