From VS Marketplace:
Helps extenders of Visual Studio by exploring the commands associated with a VS Package.
The VSCT (Visual Studio Command Table) PowerToy is a read-only viewer for Visual Studio 2010 that you can use to explore the commands associated with a VSPackage, and with Visual Studio itself. You can quickly search for any existing commands in the Visual Studio IDE. By browsing through the command groups, GUIDs and IDs, priorities, and other properties of existing commands, you can more easily place and integrate the commands of your own VSPackage.
