Hi....please help

I have read the "User Interface Customization Guide" and i customized the
CCStd, such that in the
My Favorites Portlet's
Action List i get links like "move","delete","rename" etc.
I am attaching a Snapshot of this(Zip format).
Hence i want the link "Lock" in the same Action list. I read the content center reference customizations but did not found about it.
Attached is the
ui_custom.xml file (Zip format) in which i made the customizations.
Thanks in advance....
