Hi Michael!
Thank you once again for your wonderful help.  Yes, I would love it if you could make a bug report 
on this!  Right now, I do not have an account on Bugzilla; but I will create one soon.  Seeing 
another example of how you do it in respect of this issue here will be helpful for my learning too!
I am new to NVDA and LO, but a long-time user of JAWS and MS Office.  I would like to transition 
away from the latter two and to the former two, and so hence these issues.  No doubt there will be 
more to come.  That said, I appreciate your very knowledgeable help on this since the end result 
will be a more accessible LO.  Surely, there will be many, many people around the world who will 
benefit!  And, thanks for your work-around solution!
Thanks!
Richard

I am using Windows 10, NVDA 2020.4 and LO 7.1.  In several places,
like in Calc's formatting toolbar, there are things called a "drop down button."
How do you activate them, and what is the expected functionality?  To
further, on this toolbar there is a drop down button for "Borders."  I
have tried pressing "spacebar" and "enter" on it, but nothing seems to
happen (activation).  What I expect to happen is some sort of a pick
list of types of borders would appear; such as single underline,
double underline and so on (functionality).
   
So, how do you activate a drop down button, and what is its functionality?
you're doing exactly the right thing and your expectation is correct, but unfortunately there seems 
to be another accessibility bug here.
I just tested this with NVDA. Pressing the space or enter keys enables a popup where you can select between different border 
types (e.g. "no border", "border only on the left", "border on all four sides",...), but the screen 
reader does not announce what is selected or say anything when changing selection using e.g. the arrow keys.
Do you want to create a bug report in Bugzilla for this? Otherwise I can do that as well.
As a workaround for now, the corresponding functionality should also be available in a dialog 
instead, e.g. for your example with the borders.
this is accessible like this:
* select cells
* right-click (or press "menu" button/Shift+F10
* select "Format Cells"
* navigate to "Borders" tab
