The topic says it all. I was looking around in the commands for VO commanders and found fastforward and rewind commands. When I perform the assigned keyboard command or trackpad gesture in keyboard help, it says it allows navigation quickly in reverse or forward direction during read all. When I go to something and press VO a to read all and press the assigned key or gesture, speech stops and it reads the next or previous word. How is this command supposed to work? As far as I know, it's not documented anywhere and doesn't have a built-in VoiceOver command with the VO keys. I would like to know what this does andh ow to use it properly.
