The IShellTabBrowserService interface has just the one method (after the IUnknown methods):
HRESULT TranslateAcceleratorTBS (MSG *, ULONG);
The IShellTabBrowserService interface is implemented in BROWSEUI version 6.0 from Windows Vista only. It appears to have been developed as a shell-specific variation of the ITabBrowserService interface from IEFRAME version 7.0 and higher.
This interface is not documented by Microsoft as late as the January 2007 edition of the Software Development Kit (SDK) for Windows Vista.
