Finally, for the Windows Narrator, Windows 11 build 23526 introduces some changes. For example, in this release, the development team has changed the default verbosity level from 2 to 3, which will now announce “Immediate Context Name and Type.” The Control context type like “list” or “toolbar” will allow users to better understand the focused control. Also, users are now unblocked from typing Traditional Chinese characters in Windows by the addition of a Traditional Chinese dictionary for detailed reading.

In the Braille side, the company notes that when navigating to any attachment in Outlook with scan mode, the narrator announces the “&” of the attachment. The same is now reflected on the braille display. If you navigate to different headings in Scan Mode using the down arrow or “Space + 4” key in Braille device, now navigating to the heading is reflected in Braille. Finally, when navigating a list with items, whenever the Windows Narrator announces the index with the menu item name, Braille display also reflects the same index values as “1 of 4.”
