Re: [libreoffice-accessibility] Sluggishness with NVDA and Calc

Hi Richard,

I can reproduce the behavior you describe, though the lag is only about 
4-5 seconds in my case.

I'd suggest to create 2 bug reports in Bugzilla to keep track of this:

* one bug report for the slowness (the first two aspects you mention)
* one bug report for the full "accessibility hierarchy of the cell" 
being announced

More technically: I've taken a first look at the first one. It seems 
that a significant amount of time is spent on retrieving/generating an 
accessible description of involved accessibility objects.

For the second issue: To my understanding, screen readers usually only 
announce the "hierarchy" of a focused object up to the point from which 
it's different from the previously focused object. One potential 
explanation for the current behavior could be that for some reason it's 
not exposed to NVDA that the previously selected cell is a "sibling" of 
the one selected afterwards, or somehow focus is on another 
accessibility object in between.

Both issues require a closer analysis from a development perspective, so 
unfortunately I currently have no idea what you could do from a user 
perspective to avoid this.

Both issues don't occur when just navigating through the spreadsheet 
using the arrow keys (i.e. without making any changes) or when using the 
Orca screen reader with the gtk3 VCL plugin on Linux.

Kind regards,
Michael
