Rename a File from an Applications Title Bar in OS X Mountain Lion

OS X Mountain Lion now lets you rename a file directly from the application it’s opened within. This feature is supported in most bundled Apple applications, including TextEdit, Pages, Preview, and others.

• Hover over the files name in the title bar until the arrow appears
• Click the arrow to pull down a menu, select “Rename”, enter the new name and hit the return key to save the files name change

The file extension remains consistent with the files format, and unlike renaming things in the Finder you can’t accidentally change the file extension too.

The quick video below demonstrates the process:

The usual methods of renaming files through Finder or the command line are still around, but if you’re saving files directly to iCloud this will likely be the preferential method from Mountain Lion onward.
