Bug Description

Test case:
1. Enable accessibility and the orca screen reader
2. Relog into Unity-2D
3. Open any application
4. Make the HUD appear (tap Alt)
5. Enter any search that returns some results
6. Move around the results with arrow keys
   -> The orca reader should read the suggestions


HUD is broken for users of orca, it does not speak the suggestions. In unity2d all the suggestions are spoken as pushbuttons but not the values of them.

I now tested with Orca master version, now following happening:
1. If I press ALT key, Orca only spokening following output: HUD pane
2. If I type a search term, nothing happening.
In Unity-2d 5.8.0-0ubuntu1 version HUD works perfect.

Confirming, we have regression here. This is related to the latest focus/highlight changes in Hud. Unfortunately these focus changes seem right and were implemented to fix some specific problems we had with Hud. We may need to develop a custom python script for Orca to handle unity-2d-shell a11y events.

If this Orca custom script are done, have chance to land in Precise
gnome-orca 3.4 series package with downstream level?

If need help the testing with Orca, I welcome help.
I report this issue in Bugzilla with Orca master branch related and
attach upstream level an Orca debug.out file?
When scheduled the Unity 5.12 release?

I attaching two file:
1. A listener Python script with Joanie doed.
2. The output log when I try using HUD with Orca.
This is not a full Orca debug file.
I doed following:
1. Run the listener script.
2. Press ALT key, and typed the leá string. In hungarian locale prewious
Orca spokened me I land the leállítás result (shutdown result in english).
3. Try press ENTER key. HUD right activated the shutdown dialog.
A very interesting thing the output log:
First time right focused the HUD text related label, but short time
focused an another object, with named panel | Hud.
I will be make an Orca debug.out file to see what happening.

This is an Orca debug.out file.

Thanks Attila. Custom script for Orca was a dead end and the main reason is all HUD results were sent as new children events, but moving over them was only producing regular input events (Up/Down keys), without context. I'm re-visiting our hud focus handling.

Pavel, when you working HUD focus handling, possible trying fix
following issue?
When an application HUD founding a dialogue presenting menu item, if I
try press ENTER key the selected search result, the activated dialogue
is not focused automaticaly.
An example reproducation steps:
1. Launch Gedit.
2. If you use english locale, press ALT key, and type prefe string.
HUD right presenting the edit menu preferences menu item. When you press
ENTER key, need press an ALT+F6 key combination to get focus the already
activated preferences dialog.
I reported this issue with bug 976393 report, and reproducable the issue
in unity-2d 5.10.

Martin, my test results is following:
HUD works right again after upgrade. I only experienced with following
1. If I write a search term and want exiting with HUD, need press two
escape key.
2. If I launch for example Gedit, use HUD to found a menu item and
exiting with HUD, some time impossible to moving the typed Gedit text
content until I not activate and deactivated main menu. Before I doing
this, my braille display I think I see "result list" or similar text.
Launcher, dash, menues activation works fine.
Alan, you experienced similar results?

As part of the big bug review for 16.04 LTS, I have tested this on 15.10 and the bug is still there.

Although 15.10 doesn't have Unity 2D, HUD results are not spoken by Orca in regular Unity.
