I’ve just found what appears to be an undocumented keyboard shortcut in Notes: Shift+Esc.
I accidentally used it when I meant to use Shift+Tab in a document in edit mode, and the document was saved and closed with no prompt.
This shortcut isn’t in the list when I press Ctrl+Shift+L in the client, and I haven’t found it (so far) by searching the Notes help and the forums.
Is this shortcut generally known, or have I stumbled onto something new?
