Hi, all, 

Presentation's navigator dialog has supported to drag & drop the object to 
modify the TAB order. Also the "Arrange" action in context menu can also 
modify the TAB order. If user use both "Arrange" and "Navigator" to modify 
the TAB order, the TAB order will be confused. 

I also found different behavior on order in 3 editors: In Word, if I 
arrange the drawing object to back/front, the order in navigator dialog 
won't be changed, also the TAB order won't be changed. In Presentation, if 
I arrange the drawing object to back/front, the order in navigator dialog 
won't be changed, but the TAB order will be changed. In Spreadsheet, if I 
arrange the drawing object to back/front, both the order in navigator 
dialog and TAB order will be changed. 

My question is: What is the correct object order in navigator dialog? The 
TAB order or z-index order? 

In my opinion, the navigator dialog should only change the TAB order, the 
Arrange should only change the Z-Index order and it should NOT change TAB 
order. Also I discussed this offline with Malte and he suggested me to 
post this topic here. We all think that the Arrange operation should only 
impact Z-Order, and the TAB order can only be impacted by Navigator 
dialog. Currently, I can't set correct TAB order and Z-Order separately 
unless I insert the objects initially with the desired Z-Order and won't 
use Arrange operation. 

Malte also provided some reference, for your reference. 

We thought it would make sense to have a logical tab order which doesn't 
necessarily match the z-Order.

Thanks a lot.
