Is there an explanation of all the Visual Studio settings that you can export as .vssettings files?

Hi, when I export my Visual Studio settings via "Tools -> Import and Export settings" from VS 2012 Professional, I end  up with the following text editor settings in the CSharp-Specific subcategory:

            <ToolsOptionsSubCategory name="CSharp-Specific" RegisteredName="CSharp-Specific" PackageName="Visual C# Language Service Package">

                <PropertyValue name="NewLines_Braces_CollectionInitializer">0</PropertyValue>
                <PropertyValue name="NewLines_Braces_ArrayInitializer">0</PropertyValue>

                <PropertyValue name="Space_AfterLambdaArrow">1</PropertyValue>
                <PropertyValue name="Space_BeforeLambdaArrow">1</PropertyValue>

                <PropertyValue name="Wrapping_IgnoreSpacesAroundVariableDeclaration">0</PropertyValue>
                <PropertyValue name="Wrapping_IgnoreSpacesAroundBinaryOperators">1</PropertyValue>

                <PropertyValue name="RemoveUnusedUsings">1</PropertyValue>
                <PropertyValue name="SortUsings">1</PropertyValue>

                <PropertyValue name="CodeDefinitionWindow_DocumentationComment_IndentBase">1</PropertyValue>
                <PropertyValue name="CodeDefinitionWindow_DocumentationComment_WrapLength">80</PropertyValue>

            </ToolsOptionsSubCategory>

I can't find any of those in the GUI and thus, I also can't find an explanation of what they do. Some seem straightforward (Space_AfterLambdaArrow) others are a mystery to me (CodeDefinitionWindows_xxx).

So, does anybody know what those settings do and where I can set them in the Visual Studio GUI?

Thanks
