Navigate webpages using live regions
Webpages can contain areas, called “live regions,” whose content is updated without refreshing the entire page. VoiceOver can detect live regions, even when the focus is elsewhere on a webpage, and speak the content in the live region as it changes.
Note: VO represents the VoiceOver modifier.
To enable all live regions, open VoiceOver Utility (press VO-F8 when VoiceOver is on), click the Web category, then select Enable Live Regions.
To enable a specific live region (if live regions are listed in the Rotor when viewing webpages), use the Rotor to move to a live region, then press the O key to turn the live region on or off.
