Exploring the Narrator October 2018 Update in Windows 10
Microsoft has added several new features to Narrator in the October 2018 update. My favorite is the updated keyboard layout, to make it feel more like other screen readers everyone is familiar with. A practice mode, tutorial, and Braille display detection have also been added.
After recording this video, I did verify that Narrator currently only supports Edge right now. It's not supporting IE well any more because IE is reaching the end of its life. Other browser support will hopefully be coming in the future.
