Sony Vegas 11 Cookie Cutter help

[issyd]

This may sound ridiculous, but as I am used to Sony Vegas 9, I am really confused with Sony Vegas 11 and the cookie cutter function and can't seem to find a YouTube tutorial which actually helps.

Basically, I am trying to get 2 clips over the top of each other, but I can't find the part of how to move the place of the cookie cutter, it is just in the center.

Any help would be greatly appreciated, I realise that isn't the best explained, if you need me to explain more, just say :P
