There is an API called MSAA (Microsoft Active Accessibility) that the toolbars would have to use to fully support screen readers.
Toad uses components provided by Developer Express Inc. Currently Developer Express Inc does not support this feature and we are not aware of their future plans in this area. Therefore, Toad does not support screen readers.
An enhancement request has been posted to the Idea Pond for future consideration. Click here to vote and/or add comments
