"Save As..." in Tahoe?

[Cave Man]

So, I do not see how to add "Save As..." to the File menu in Tahoe. I've gone to Settings > Keyboard > Keyboard Shortcuts, but there is no plus sign to add it like there was in previous macOS versions. What am I missing?

"Save As..." is available in all apps with a File>Duplication command. If you hold down the option key, "Duplicate" turn into "Save As..."

macOS has never let users edit or add menus items.
