The "Introduce Constant"(Ctrl+Alt+C) is helpful for "Refactoring, nested classes"

Yes. Exactly this. And you might need Ctrl + T to refactor individual entries as well.

Thanks for the tip. I used Refactor - Introduce Constant, which worked -but I had to move all the constants manually into the "Constants" class and add Constants.BLA_BLA before every occurence of the constant manually. Is there an easier wy to do this?
