I haven’t used it extensively but they way I’ve seen it used it with the TTS button that stays on screen. You activate it and then highlight what you want read with a general selection box. The other method is activate it and just press play for it to read everything on screen. I’m not sure if it’ll autoscroll if you are using it for a long article on a webpage
This was not something on my radar in the least bit but I’m here for it!
