What do Visual Studio viewport icons mean?

Question

What do all view and overlay window icons in Visual Studio mean? Is there any legend on the MSDN page?

Answer 1

Icons identify the type of object being observed; the same icons are also used in IntelliSense, the class and the object browser (and in Visual Studio 2012, advanced solution explorer).

In the MSDN icon overview: View icons and object browser icons ( in Visual Studio 2012 , they are similar but different from each other).

Answer 2

For VS2013, here is the link to the icon:
