I see the same behavior on Sierra.
Bottom line is that it appears a bug was introduced in 10.10.6 and
Sierra 10.11 where use of control option up/down arrow in a list is
sending accessibilitySetSelectedAttribute:1 each time rather than
waiting for the user to press control option space to select a list item.
Note that Finder in it's list view is not useful as a test case; it's
behavior is different.
I wish someone could try this test on 10.10.5 or earlier:
- download SwingSet2.jar from
http://cr.openjdk.java.net/~ptbrunet/SwingSet2/SwingSet2.jar
- if you don't have Java build 130 or later download it from
https://jdk9.java.net/download/
- make sure VoiceOver is set up as follows:
- System Preferences, Accessibility, VoiceOver, Open VoiceOver
Utility, Navigation
- In Grouping behavior: Ignore groups
- Keyboard focus follows VoiceOver cursor: checked
- VoiceOver cursor follow keyboard focus: checked
- start VoiceOver
- start SwingSet2: java -jar SwingSet2.jar
- click the ListDemo toolbar button to select the ListDemo
- press control + option + right arrow 10 times to move focus to the
text above the list box
- press control + option + down arrow 1 time to move focus to the list
- press shift + control + down arrow to interact with the list
- press control + option + down arrow to move to the next list item
- multiple list items should not be selected
Extra effort, but these work OK
- use control option space to single select a list item
- use control option command return to multi select a list item
It would be helpful to know if this is recognized to be a bug.
Thanks, Pete
