Text deleted or changed in Notes can now be reversed from the keyboard.
- Command-Z and Control-Z undo the latest editor change.
- Command-Shift-Z and Control-Y redo it.
- The shortcuts use the existing Tiptap and ProseMirror transaction history, preserving text, selection, formatting, and list structure together.
- Undo and redo remain ordinary editor updates, so the restored note follows the same autosave path as typing.
No custom parallel history or reconstruction layer was added.
