Camera button not working? and questions on other buttons

[Jedi]

i installed pdaj's wm6.1 image on my xv6700.

Why doesnt the camera button work?

In the 'buttons' menu:
1) why isnt there an option for the camera button? How do i add it?
2) what's the button that has CommManager assigned to it?
3) Where is the Cyberon Voice Commander button on the xv6700?
