change toolbar name

Hi

I try to change the name of the toolbar of my addon.
I tried it according to
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/WritingUNO/A
ddOns/Toolbars
It works fine for Writer/Textdocuments
But I'm not able to get it working for Calc/Spreadsheets.

Whats the <Module> for spreadsheets?
I guess my filename is wrong
Or do I have to make changes to the ...WindowState.xcu when using it for
Calc?

Thanks for your help,
  Martin
