The shader:

Shader "Standard"

{

    Properties

    {

        [LM_Albedo] [LM_Transparency] _Color("Color", Color) = (1,1,1,1)  

        [LM_MasterTilingOffset] [LM_Albedo] _MainTex("Albedo", 2D) = "white" {}



        [LM_TransparencyCutOff] _AlphaTestRef("Alpha Cutoff", Range(0.0, 1.0)) = 0.5



        [LM_Glossiness] _Glossiness("Smoothness", Range(0.0, 1.0)) = 0.0

        [LM_Metallic] _Metallic("Metallic", Range(0.0, 1.0)) = 0.0

        [LM_Metallic] [LM_Glossiness] _MetallicGlossMap("Metallic", 2D) = "white" {}



        _BumpScale("Scale", Float) = 1.0

        [LM_NormalMap] _BumpMap("Normal Map", 2D) = "bump" {}



        _Parallax ("Height Scale", Range (0.005, 0.08)) = 0.02

        _ParallaxMap ("Height Map", 2D) = "black" {}



        _OcclusionStrength("Strength", Range(0.0, 1.0)) = 1.0

        _OcclusionMap("Occlusion", 2D) = "white" {}



        [LM_Emission] _EmissionColor("Color", Color) = (0,0,0)

        [LM_Emission] _EmissionMap("Emission", 2D) = "white" {}



        _DetailMask("Detail Mask", 2D) = "white" {}



        _DetailAlbedoMap("Detail Albedo x2", 2D) = "grey" {}

        _DetailNormalMapScale("Scale", Float) = 1.0

        _DetailNormalMap("Normal Map", 2D) = "bump" {}



        [KeywordEnum(UV1, UV2)] _UVSec ("UV Set for secondary textures", Float) = 0



        // UI-only data

        [KeywordEnum(None, Realtime, Baked)]  _Lightmapping ("GI", Int) = 1

        [HideInInspector] _EmissionScaleUI("Scale", Float) = 1.0

        [HideInInspector] _EmissionColorUI("Color", Color) = (0,0,0)

        [HideInInspector] _EmissionColorWithMapUI("Color", Color) = (1,1,1)



        // Blending state

        [HideInInspector] _Mode ("__mode", Float) = 0.0

        [HideInInspector] _SrcBlend ("__src", Float) = 1.0

        [HideInInspector] _DstBlend ("__dst", Float) = 0.0

        [HideInInspector] _ZWrite ("__zw", Float) = 1.0

    }

It have 4 modes: Opaque, Cutout, Fade, Transparent
I want to switch between this 4 modes and affecting the specific gameobject shader rendering modes in the hierarchy using a button.

Each click on the button will switch to the next mode.

And in EditorWindow

The script:

using System.Collections;

using System.Collections.Generic;

using UnityEditor;

using UnityEngine;



public class ChangeShaderRenderingModes : EditorWindow

{

    public enum BlendMode

    {

        Opaque,

        Cutout,

        Fade,

        Transparent

    }



    [MenuItem("Tools/Change Rendering Modes")]

    public static void ShowWindow()

    {

        GetWindow<ChangeShaderRenderingModes>("ChangeRenderingModes");

    }



    private void OnGUI()

    {

        if(GUI.Button(new Rect(50,50,50,50), "Switch Mode"))

        {

            var objects = Selection.objects;

        }

    }

}

I'm not sure how to make the switching and accessing the shader parameters.
