How can you get Apple's attention about this? I now have to dulicate and rename it. On top of that it duplicates it in the current folder. In the past I could duplicate, rename, and move all with one menu item...Save As. What makes me mad is that I have been working with Apple products for almost 30 years. I normally love everything they do (with the exception of actually dumbing down iMovie). This has got to be the first time I actually have been mad about something. Saddly, I know Apple is not listening. Save as would have been returned to Pages in an update of some sort if they were. I guess I will fork out the money for a better product.
No, you don't have to duplicate then save, entering a new name, as long as you are using Mountain Lion. It has been mentioned more than once in this thread alone. Hold down the Option/alt key while clicking the File menu & you will see Save As… & its keyboard shortcut, ⌘ ⌥ ⇧ S.
Be aware that autosave will save any changes to the original document if you haven't checked the option to ask to save changes in System Preferences > General.
Be aware that "Save As..." is, in reality, a bug described as a feature.
Saving a fork of a file via the current 'save as' results in not only both forks of the file saving as the edited version but also the version open for edting calls itself by the old name. If you leave it open and attempt to open the newly created fork, the original version jumps to focus.
If it ain't broke, don't fix it. Apple have breached a long standing understanding with their users in getting into this 'trouble' in the first place. I am an Apple user since the 1970s and a mac user since 1986. I don't like it when 'stuff' like this happens.
