Press Cmd+U to open a new notes window, then switch over to the Markdown view (click MD at the bottom of the screen) - the default text says you can press Cmd+Shift+D to start editing. That shortcut also works when in TXT mode. Is this what you are asking for?
Seems odd the text mode default content doesn't mention it.

When I press Cmd+U to open a new notes tab, the keyboard focus is in the location bar. The above keyboard shortcut doesn't work until I click into the content area.
Expected behavior: when i press Cmd+U to open a a new Notes tab, I expect the input focus to be in the newly opened tab so I can interact with the page contents right away.
