Hello,

I am trying to fix accessibility of LibreOffice, specifically searching for text attributes in the main text component (which is a AXTextArea). I want e.g. VO-Cmd-B to find the next bold text portion.

AXAttributedStringFromRange is properly implemented - attributes are correctly announced as one moves cursor through the text with arrows.
AXStyleRangeForIndex is reported as a supported parameterized attribute in accessibilityParameterizedAttributeNames. I did not test whether this method returns correct results for this attribute, but based on logging of NSAccessibility method calls, this attribute is never requested.

Yet searching for e.g. next bold text using VO-Cmd-B does not work - VoiceOver announces "Bold text item not found". Also from logging queried attributes it is clear that AXStyleRangeForIndex is never queried even though it is reported as supported parameterized attribute.

Please find (at the bottom of this email) the attributed string returned for AXAttributedStringFromRange for a sample document I created. E.g. when having cursor at the beginning of the document, first press of VO-Cmd-B should take one to "is" and second press to "accessibility".

I would appreciate any tips or pointers on what to try or where to look to fix the problem of text attribute searching not working.

Thanks,
Boris
