Hi Sergey, Probably we should stick with generic keys to go thro' java
components like the TAB key traversals. Because on Windows, I just can't get
focus onto the progress bar without explicitly setting the focusable to
true(like in fix).
Ctrl+option+up/down/left/right is specific to the implementation of voice over
on Mac and we do not have similar alternative ways for Windows(for JAWS)
platform.
Thanks and regards,
Shashi

Hi, Shashi.
I checked it on the fresh build of jdk/client, and confirm that it is possible
to select progress bar using ctrl+option+up/down/left.
Screenshot is attached to the bug.
