Tile visuals to focus on the VoiceOver cursor on Mac
When you tile visuals, the screen is dimmed so that only the item in the VoiceOver cursor is visible in the center of the screen. This feature can be helpful when you’re first learning to use VoiceOver.
Note: VO represents the VoiceOver modifier.
Tile visuals: Press VO-F10.
The caption or braille panel moves to the top or bottom center of the screen, while the item in the VoiceOver cursor moves to the center of the screen and the rest of the screen is dimmed. As you navigate, the VoiceOver cursor stays in the center of the screen and you see the item you navigated to.
Stop tiling visuals: Press VO-F10 again.
