Adding toolbar/menu command to Excel using C#
 

In Excel, when I select Customize... on the Tools menu, and then select the
Commands tab, many commands appear which the users can add to the Excel
menus and toolbars.

How can I add a new command to this list?

I'm implementing the project using C# and Office 2000, and need to support
Office 2000 and later.

Thanks,
Aaron Queenan.
