Use a braille display to show the VoiceOver cursor on Mac
The cells of a braille display show the content of the line where the VoiceOver cursor is focused. If your braille display has dedicated status cells, VoiceOver can use them to show additional information about the line.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
Open VoiceOver Utility (press VO-F8 when VoiceOver is on), click the Braille category, then click Status.
Select one or more of the tickboxes.
If you don’t select any tickboxes, status isn’t shown, and the reading cells are used to show the content of the current line.
To display an expanded braille description of each dot in the cell, press the router key above a status cell. To exit the description, press any other router key.
If your braille display doesn’t have status cells, VoiceOver uses the first one to three cells on the left or right to show status. VoiceOver reserves another cell, which it leaves blank, as a separator between the status cells and the other cells.
