The ActivateTool method is a static method of the VertexTool class within the Editor.MeshEditor namespace. This method is used to activate the vertex editing tool in the mesh editor, allowing users to move, rotate, and scale mesh vertices. It is decorated with the Editor.ShortcutAttribute, which assigns a keyboard shortcut to the tool for quick access.

To use the ActivateTool method, simply call it from the VertexTool class. This will activate the vertex editing tool in the mesh editor environment. The method does not take any parameters and does not return a value.

The method is static, so it should be called on the class itself rather than on an instance of the class.
