How to import keyboard shorcuts / How to change theme color in Ubuntu 12.04

Hi Guys,

As the subjects says it, i wanted to know how i can import keyboard shortcuts.
I didn't find a function for it.

And maybe there's someone out there who can answer me the second question.
I don't want to switch to KDE only for a color change, so has anyone an idea how to
change the color of the Programm in Unity?

BTW: I'm using Kdenlive 0.8.2.1
