In the latest version of iTunes (version 11), you can use Command + 1 through Command + 7 to switch the view between different sections of your iTunes library.
- Cmd + 1 = Music
- Cmd + 2 = Movies
- Cmd + 3 = TV Shows
- Cmd + 4 = Podcasts
- Cmd + 5 = iTunes U
- Cmd + 6 = Books
- Cmd + 7 = Apps
These iTunes 11 shortcuts will only work if the corresponding sections of your iTunes library are enabled in the General pane of your iTunes preferences.

Super insightful and fresh perspective.
Well explained and easy to follow.
So glad I stumbled upon this.
Looking forward to your next post!
Truly a masterpiece of content.
