iTunes 4.5 and iTMS style arrows

Thank you Jean for the tip
iTunes 4.5 introduced a new feature that however clever, can become quite annoying, quite fast: those arrows present in the library that link the former to the Music Store's information about artists, related songs, etc.
But, if you click on one of those arrows while maintaining the ALT key depressed, you will jump within your own library instead of to the iTMS (which would just frustrate non-US users anyway).
So, while using the ALT key each time is fun, you can change the default behavior of those arrows (taken from Mac OSX Hints).
Open the terminal and type the following command :
defaults write com.apple.iTunes invertStoreLinks -bool YES
If you ever want to get back to the original behavior, enter :
defaults write com.apple.iTunes invertStoreLinks -bool NO
Easy, painless.
