Websphere Commerce - modify Accelerator

Anybody has worked with Webphere Commerce v6 ?

I am looking to modify ( add ) functionality to be used by CSR in Accelerator.

I have to add a button with some existing buttons but i cannot find the code where the existing buttons are , the clsoest i came was parent.getButtons(); between script tags.
How do i locate the parent? ( its javascript )

google or infocenter wasn't much help.

Ok so i found it .. i'll just post here for future reference ( and if someone else ever needs )

Its in xml file under <toolkit_install_dir>\xml\tools\csr
between <button>tags
