@Qchristensen, what do you think about this?

I think we'd need to see solid real world use cases for this.

Do we know what objects the original person had in mind? The elements list can be used to jump to charts, which is probably the best real world case I can think of. Objects such as shapes have accessibility issues anyway. Theoretically, if and when we were able to get more information about shapes (not to mention insert them), having a category to reach them on the elements list could theoretically be useful. Ditto pivot tables, and sparklines (though sparklines could possibly be put in the "charts" section, since logically, they are essentially simple, one cell charts, even if they behave differently).

There are no steps to reproduce so i suggest closing it. Button form fields set as macro are accessible in browse mode by pressing f. Charts are accessible with NVDA by pressing nvda+f7 and choosing a chart. I think the only usecase I am aware of is filter cells and macros which change the value for a certain cell (i.e. color etc) but which are not defined as a certain control.
Drop down menus are also accessible and you can press alt+down arrow to open the dropdown list.

There are other objects such as pictures, shapes and slicers, but there are specific issues for shapes and slicers at least

Slicer: #6605
Shapes: #7969

So yes, I'll close this one and specific objects can be dealt with under individual issues.
