Visual Studio has a concept of commands, i.e. actions executable by pressing a shortcut, entering them on the Command Window etc.

Visual Studio itself documents its commands (at least some of them) but I was wondering if there is a unified way to get information about any command, e.g. coming from ReSharper, TestDriven.NET etc. What I'd like to see for every command:

• Textual description of the command
• List of parameters and their types/allowed values

I've never developed a VS addon / extension so am not sure if this question even makes sense but from the user perspective, some documentation would be greatly appreciated.

BTW, is the Command Window the best place to get at least an overview of all the commands available? Tools>Options>Keyboard is another place where I can see shortcuts also but the UI is not very convenient...
