Context menu alterations for discussiongroup layoutset(forum)

Hey all,

For the discussion group layout set(i.e forums), I am unable to make out where I have to make changes in System Configuration >UserInterface >settings >layoutset >discussiongrouplayoutset to delete some options from the context menu against the forum folder. If I have to make changes in the breadcrumb, I came to understand that I will have to change the collection renderer settings and its corresponding ui command group. But this context menu is placed just beside the folder name. If I have to make some changes to this particular context menu(like I wud want to remove some options like clipboard, Createlink etc) How do I go about it? Plz suggest me with some help.

Regards,

PP.
