Use VoiceOver on your Mac with braille display router keys
Many braille displays have router keys above the braille cells that you can use to move the VoiceOver cursor or perform different actions.
Move the VoiceOver cursor to an item
Press the router key above an item in a line of braille to move the VoiceOver cursor to that item.
Perform a control’s default action
When the VoiceOver cursor is on a control, press the router key above it to perform the control’s default action. For example, to click a button, press the router key to move the VoiceOver cursor to the button, then press the router key again to click the button. You don’t have to touch the computer’s keyboard.
When you’re reading or navigating text, press a router key to move the VoiceOver cursor to that location in the text.
Press the router key above the first character of text you want to select to position the insertion point in front of it. Press and hold the Shift key on the keyboard, then press the router key above the last character of the text you want to select. You can also assign a VoiceOver command to use the Shift key on a braille display.
Display expanded braille descriptions
Press the router key above a status cell to display an expanded braille description of each dot in the cell. To exit the description, press any other router key.
