I want Mp3tag to be able to transform the ID3 tags to **Mixed Case** , but I don't want prepositions/connectors to start with a Capital letter, but a lowercase one.  
How I can do that?  
_(the, of, from, a, an, etc...)_

Thank you. 🙂

Thank you, searching in the forum I found useful information. 🙂  
How do I use Regular Expressions? What is the method?

Great! I used the RegEx in [this post](https://community.mp3tag.de/t/2086/4) provided by **dano** , and placed the Action after the "Case conersion" one. Now it works great.

Thank you! 🙂
