Here is a Mac 101 tip for novice Mac users.
Running Pages in Mac OS X Lion means you never have to worry about saving a document, it just happens automatically. While this is wonderful, this new feature has caused me to scratch my head a few times while I acclimatise to this simple, but quite different way of saving documents.
In previous versions of Mac OS X, when working on a document, very often I would hit "Save as..." from the File menu to (double) check where I had saved my document or to rename my document as it went through various titles. The problem I've found with Versions and Auto Save in Lion (or where I've struggled to adjust!) is that once you've created and titled a document by saving it, you're left with "Save a Version," which means you can't locate where you've saved your document or rename the title of your document from within Pages.
Fortunately, there's an older feature of Mac OS X that helps you easily identify where you've saved your document. And I'm not talking about going to Finder or Spotlight to search for it. You can view the root path of your document right from within Pages. Simply hit and hold the Control key on your keyboard (or right-click on your mouse) and click on the title of your document at the top of the Pages window. This will bring up the root path of your document so you can easily see where you document is stored on your computer.
Note that you must aim carefully when clicking on the menu bar. If you're in an app that supports Versions, a click on the right-hand side will reveal the Versions menu, and that's not what we want in this instance. If you see the disclosure triangle appear beneath your cursor, move a few pixels to the left.
