Use a braille display to review VoiceOver announcements on Mac
VoiceOver sends announcements to your braille display about events that aren’t represented visually on the screen, such as when an app in the background needs attention. VoiceOver stores up to 30 announcements in the history, with the most recent one listed first.
Note: VO represents the VoiceOver modifier.
Before you can review announcements, you must set an option to show general display status. To do so, open VoiceOver Utility (press VO-F8 when VoiceOver is on), click the Braille category, then click Layout.
On the status cell that shows general display status, dot 1 indicates whether there are new unread announcements. Dot 2 indicates whether the current announcement has already been read.
If you assigned the Announcement History command to a braille display key, press that key to show the most recent announcement in the reading cells.
To move through the announcement history, press the Up Arrow key to move through announcements until you reach the oldest one; press the Down Arrow key to move forward through announcements until you reach the most recent one.
When you’re done reviewing announcements, press any router key above the announcement to redisplay the current line.
