To create a new document, navigate to the File menu and select New. Archimedes can also open
mtex files. You can save, rename, move, and duplicate documents from the File menu. Archimedes has support for macOS's Versions feature so the Revert To menu can be used to revert to an older version of your document if you make a mistake or want to reference an older copy.
