Yay new book! Pre-order it here.
КартиниI was using DoubleCommand to swap my Command and Option keys on my Logitech K800 Windows keyboard and discovered that the app didn’t record my preferences anymore. Thats when I also discovered that OS X Lion supports key swapping right in the Keyboard preferences pane.
Head over to system preferences, select Keyboard, click Modifier Keys and there you go. Just swap Command and Option. Save it and it will remain forever thus.
