A good reminder again about the future-proofed nature of Markdown format notes. They are essentially plain text and will be read my many apps well into the future.
Also true that Markdown’s “shortcuts” for headings, lists, are largely universal, so that as you may switch apps or operating systems you don’t have any different “shortcut” keys to remember.
