Modify ccstd to remove a toolbar button

System

Hello,

We have TeamSite 7.3.1 on windows 2008 R2 x64 and in the standard view, I'm attempting to remove the "Publish Workarea" button(Part of the Global toolbar). I can't find the process or method for accomplishing this in the TeamSite 7.2 User Interface Customization Guide.

I've even tried to use css to hide the button, but modifying /web/base/styles/custom.css doesn't seem to have any impact.

Any help on where to start is greatly appreciated.
