Rename a file from an applications title bar

Did you know that OS X 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 title bar
• Click the filename to pull down a menu, 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 usual method of renaming files through Finder is still around, but if you're saving files directly to iCloud this is likely the preferential method.
