How to disconnet arrow-keys in a JTabbPane

Hello!
I try to bulid an app that uses a JTabbPane. I would like to be able to use the tab-key and shift+tab-key to switch among the tabbs in the JTabbpane.

I would also like to be able to use the left and right-arrow keys to some special task. But now those keyevents shifts the tabbs as the tab-key.

Does any one know how to disconnect the JTabbPane to listen for arrow-keys?

Below is a quick app that describes this.

Best regards
Fredrik
