That matches what I see with Orca and the gtk3 VCL plugin (interface variant) on Linux. (The Qt-based VCL plugins don't expose that information yet. I might look into that while working on the Windows implementation, since they'll be using the same IAccessible2 text attribute implementation in LibreOffice then.) On an unrelated issue, the accessibility of comments in LibreOffice Writer was recently raised on the Orca mailing list. Change tracking (reporting of insertions and deletions) is an associated feature that has not, to my knowledge, been made accessible to screen reader users in LibreOffice. Anyone needing to make effective use of comments and change tracking using a screen reader would likely need to turn to a proprietary office application instead, for which the necessary API support has been in place for some time. Thanks for mentioning that. In a quick test with Writer and Accerciser to inspect the accessibility tree, I see "text-tracked-change:deletion"/"text-tracked-change:insertion" text attributes being reported for the portions of text that have been removed/added. For comments, there's a comment object as a child of the paragraph object and that exposes the text of the comment. But it's likely that more is missing to properly expose that on the LibreOffice side and/or process that information on Orca side. (And at a quick glance, I don't see any corresponding text attributes in the IAccessible2 spec that could be used on Windows.) Without an existing specification on how these should be exposed, this will likely need some thorough considerations (and discussion with everyone involved) on what's the best approach for this.

I gave him my nputs, he now tries to give a better technical base and reproduction scenarios. To sum up my current feeling, the main problems is the style dialog, where browsing with the caret is very difficult to edit and tweak styles, the browser (f5) whose behaviour is not stable, and some dialogs where browing is very hard (eg. this to number chapters, in Tools menu). The style dialog being the most problematic as what is sent to the accessibility infra is really difficult to use for a screen reader, I tried to run an automated test suite producing code to reproduce scenarios from the at-spi events and this dialog sent really not relevant info. Actually I think something needs to be explained: using screen readers like Orca or NVDA, we consider as accessible information what may be reached via the caret, ie. what you can move with tab key or the arrow keys. Using advanced features to access to the information, eg. object navigation or flat review, is not optimal. It might work, but not everybody know it and is it considered as a kind of hack to workaround accessibility limitations. For dialogs that present information without allowing to change anything, like the case of the word count dialog ("Tools" -> "Word Count") discussed here: Would you still expect to be able to navigate within the dialog text using tab or arrow keys? Yes. In comparison, in Thunderbird, when having a dialog (a question for instance), the caret can switch to OK, Cancel, and the message box, enabling to say it. Of course in such case not other ineraction is possible, but the movement is and makes it accessible.

Most of the window seems taken up with a needlessly (to me) long explanation of what word count does. The only way I've found of hearing the actual word count is to use insert+b to get NVDA to read the whole dialog box, and the word count comes right at the end. Little thing I know, but rather irritating if one is trying to keep tabs on the number of words, and having to read every time that this shows the word count of the current selection and the whole document, and that this is automatically updated as you type. Useful to know once of course, but annoying to have to hear every single time. I've just tested this under Linux with Orca, and I can use the screen reader's review commands to read the dialogue. Starting from the bottom gives me the character counts (with and without spaces), and the word count. Actually I think something needs to be explained: using screen readers like Orca or NVDA, we consider as accessible information what may be reached via the caret, ie. what you can move with tab key or the arrow keys. Using advanced features to access to the information, eg. object navigation or flat review, is not optimal. It might work, but not everybody know it and is it considered as a kind of hack to workaround accessibility limitations. The explanation of what word count does is not shown in the dialog, but set as the accessible description of the dialog. And when an accessible description is set for a dialog, NVDA announces that description instead of the dialog content. NVDA source code for this: https://github.com/nvaccess/nvda/blob/a380b6a76a0a29df32e57c1bd974b11a895ac0c8/source/NVDAObjects/behaviors.py#L151-L156 On top of that, the same text was set for both of the buttons, so when pressing NVDA+B, the text would get announced three times: once as the accessible description of the dialog at the very beginning, and then once when each of the buttons is announced. At least the latter seems wrong, so I've submitted a change to drop that: https://gerrit.libreoffice.org/c/core/+/157637 One approach to avoid announcing the explanation each time and announcing the content instead would be dropping the accessible description for the dialog, since it's still easily possible to get that info by pressing the "Help" button in the dialog. I've submitted a change to do that, but am currently waiting for feedback from the documentation/help team on whether that's OK, since that would also mean that the text is no longer shown as a tooltip when extended tips are enabled in the LibreOffice options. As a potential alternative, if you're primarily interested in the document word count, that info is more quickly available in the status bar. NVDA+End will announce it from NVDA 2023.2 on. (This was implemented in NVDA for LibreOffice in https://github.com/nvaccess/nvda/pull/14933 .) As a side note, when I tested that just now, I noticed that this needs another update to work with the current development version of LibreOffice and to make the functionality work with status bars in dialogs as well. Pending/Suggested changes: https://gerrit.libreoffice.org/c/core/+/157658 https://gerrit.libreoffice.org/c/core/+/157659 https://github.com/nvaccess/nvda/pull/15592 But as far as I can tell, if you're using NVDA 2023.2 and LibreOffice 7.5 or 7.6, this should work fine. My second point is about automatic spell checking. I find that my screen reader will only inform me of a spelling error if the cursor happens to land on the word. I don't know if I can make it any clearer, but for instance if reading a line back in this email, NVDA will announce "spelling error" each time it encounters a mis-spelled word. In LO writer, I will only be told each mis-spelled word when the cursor is on it. Pretty little thing this, but it would be nice if it could be corrected. I think that's a screen reader issue. You should probably report it to NVDA. Unfortunately I am not sure. I Cc Joanmarie Diggs, main Orca developer, who can confirm or give you technical explanations.

Little thing I know, but rather irritating if one is trying to keep tabs on the number of words, and having to read every time that this shows the word count of the current selection and the whole document, and that this is automatically updated as you type. Useful to know once of course, but annoying to have to hear every single time. I've just tested this under Linux with Orca, and I can use the screen reader's review commands to read the dialogue. Starting from the bottom gives me the character counts (with and without spaces), and the word count. The explanation of what word count does is not shown in the dialog, but set as the accessible description of the dialog. And when an accessible description is set for a dialog, NVDA announces that description instead of the dialog content. NVDA source code for this: https://github.com/nvaccess/nvda/blob/a380b6a76a0a29df32e57c1bd974b11a895ac0c8/source/NVDAObjects/behaviors.py#L151-L156 On top of that, the same text was set for both of the buttons, so when pressing NVDA+B, the text would get announced three times: once as the accessible description of the dialog at the very beginning, and then once when each of the buttons is announced. At least the latter seems wrong, so I've submitted a change to drop that: https://gerrit.libreoffice.org/c/core/+/157637 One approach to avoid announcing the explanation each time and announcing the content instead would be dropping the accessible description for the dialog, since it's still easily possible to get that info by pressing the "Help" button in the dialog. I've submitted a change to do that, but am currently waiting for feedback from the documentation/help team on whether that's OK, since that would also mean that the text is no longer shown as a tooltip when extended tips are enabled in the LibreOffice options. As a potential alternative, if you're primarily interested in the document word count, that info is more quickly available in the status bar. NVDA+End will announce it from NVDA 2023.2 on. (This was implemented in NVDA for LibreOffice in https://github.com/nvaccess/nvda/pull/14933 .) As a side note, when I tested that just now, I noticed that this needs another update to work with the current development version of LibreOffice and to make the functionality work with status bars in dialogs as well. Pending/Suggested changes: https://gerrit.libreoffice.org/c/core/+/157658 https://gerrit.libreoffice.org/c/core/+/157659 https://github.com/nvaccess/nvda/pull/15592 But as far as I can tell, if you're using NVDA 2023.2 and LibreOffice 7.5 or 7.6, this should work fine. My second point is about automatic spell checking. I find that my screen reader will only inform me of a spelling error if the cursor happens to land on the word. I don't know if I can make it any clearer, but for instance if reading a line back in this email, NVDA will announce "spelling error" each time it encounters a mis-spelled word. In LO writer, I will only be told each mis-spelled word when the cursor is on it. Pretty little thing this, but it would be nice if it could be corrected. I think that's a screen reader issue. You should probably report it to NVDA. I can reproduce this, e.g. with a paragraph containing this text: "Hello world, wrrong spelling." Moving to that paragraph using the cursor up/down key, NVDA announces "spelling error" when using Word right away, but not for Writer. I plan to take a look into that, but cannot say yet when I'll get to it. My third problem is potentially quite important, because if you're using a braille display, if you prefer to work without speech, which I often do, it can make editing and proofing quite challenging. Along the top of a braille display is a row of buttons called 'router keys'. When pressed, the cursor is moved to that place in the document. Cursor routing keys worked for me under Linux with a braille display and the Orca screen reader when I last used them. It might be a Windows or NVDA-specific issue. Can you please provide a detailed description of how to reproduce this issue? (What are the exact steps you're taking? What is the actual outcome? What is the expected outcome?) I noticed that NVDA has a braille viewer ("Tools" -> "Braille Viewer") so tried to reproduce with that, since I don't have any actual hardware. How
