Hey I have new Lenovo z570 laptop recently. It has a unique keyboard. I am able to use it but not to its full capabilities. I am unable to map some of the 'extra' keys to their respective functions. There is no separate keyboard model for lenovo z570. I would like to configure this keyboard properly and give back to the ubuntu repos for storage so that later someone else using the same laptop can use my configuration that I have set. 

**How do I do that?**
