Open an empty Writer document.
Write some text with one wrong written word.
Press F7 for the spelling dialog.
The dialog sets the focus to "Correct".
This behavior is nice for people who would see the content of "Not in dictionary", but if you have to work with a screen reader you have to jump back to "Not in dictionary" to hear the content of the wrong sentence.
But this is only the first part of accessibility problems in this dialog. It's also part of bug 102044.
Agree, it's quite inconvenient - but it can be done, user needs to press shift-tab a few times (in any case, would likely be a behaviour change conditional to screenreader users) -> UX advise appreciated, and to me more an enhancement than a bug.
If you are using a screenreader, you have to make sure, that unnessesary typing is avoide, so you can work quicklyand the actual behaviour in this dialoque slows the work for screenreader users. Should be changed.
Additional: The mispelled word is only noteable, when the screenreaders announces color change, which is not regular.
