Switching Cameras in 2.5?

How the heck do you switch cameras in 2.5? I try the good ol’ “CTRL NUM 0” and get nothing, I looked around, couldn’t really figure it out, this new interface is a strange thing to an old user like myself. I’m using one of the latest build “SVN 23080” from Graphicall.

Anyone know how this is done? Is there a 2.5 wiki being put together that I can get a peep at or something that answer some of these simple yet critical question?

remember that there not finished with 2.5 and a lot of features might be incomplete or even changed.
