Word does not have the term "Quick Style Set"
It is not used on the domain Welcome
Ed Bott didn't use such a term in Microsoft Office Inside Out:2013 Edition, published through MicroSoftPress.
It seems to be your own creation despite no precedent from MicroSoft, Sarah Barnhill or anyone else.
However, the term is used in a Youtube video for a different item. https://www.youtube.com/watch?v=liQFbLo9Cx0, which is also applied incorrectly.

Even when Right Clicking on the style to add to the Gallery, it is "Add to Style Gallery" or through the modify style window, "Add to the Styles gallery"

Style Sets are listed in the Design Ribbon. A Style Set can be selected. Hovering over a Style Set will give the name of the Style Set. If you open the Style Pane and show All Styles, it can be more apparent that even those styles not in the Styles Gallery change. Since most of MS styles are still similar, it can be more obvious if a Style is edited so the preview change is even more obvious.
OR, you can remove ALL the Styles from the Gallery and then Change the Style Set on the Design Ribbon. Your statement indicates then that NOTHING will change because none of the Styles are in the Gallery.

Her name is Suzanne Barnhill if you are talking about the Word MVP.

Did you read the quotation I posted from Faithe Wempen?

The term Quick Styles originated with Microsoft, not me.

Have you looked at the storage location for Style Sets?
It is the QuickStyles folder.
Did you try either of the experiments?

Yes, the Styles Pane allows preview of Styles. It has since, I think, Word 2000. I usually keep this turned off but the dropdown still has it.


This is confusing, I know, it took me years to figure it out.
Here is a good blog:
Behind the Curtain (II) - Styles, Doc Defaults, Style Sets, and Themes - Jonathan Bailor - blog - How do document defaults relate to the Normal style? How do Style Sets relate to Styles? How do Themes relate to Styles? - It is by one of the originators of the concepts and explains that the style sets only change styles in the Quick Styles Gallery.
