Please adding a value data "Rightclick's standard menu when right click on empty space on taskbar". (Add to Mouse Button Control)

I'm not sure I understand the suggestion. What are you referring to as the "standard menu"? The menu below?

Yes, yes, this is what I mean. :)

Showing the menu is the default behavior. Why would you need an option for it?

Right click is very quick action so I want to do it with an more heplfull value as Alt+Tab. And I going to shift+right-click to show "standard menu".

Oh, WOW! This is exactly what I want. Thankyou so much!
