toggle shaded vertex color

ok That is easy to do

ok

That is easy to do :)

Here is the macroscript.
Run the macroscript one time and add a shortcut or quad menu (for example) by using the category "toolBox"

code:

macroscript shadedVCToogleMacro
category:"toolBox"
buttonText:"shadedVC"
toolTip:"shadedVCToogle"
(
on execute do (
for obj in selection where ( superclassof obj == GeometryClass and classof obj!= Targetobject ) do ( obj.vertexColorsShaded= (not obj.vertexColorsShaded) )
)
)

This script don't activate the vertex color mode in itself. I suppose that it is what you want?
