So, Yosemite caused most OS-X apps to loose Save As... in favor of Duplicate or whatever. Here is how to get Save As... back.
- System Preferences -> Keyboards -> Shortcuts -> App Shortcuts
- Add a shortcut called Save As... as Command-Shift-S
- Assign Command-Option-Shift-S to Duplicate Now, Duplicate will magically be hidden behind Save As... in the way that Save As... was previously hidden behind Duplicate That is, when you hold the option key down, Duplicate changed to ``Save As...``. Otherwise they'll be shown together in the menu.
