(Official WG Response)
Thanks for the comment.

The first part of your comment is that AT may use single-key keystrokes. The SC is not designed to apply to keystrokes implemented by AT, which is intended to be clarified by the "If a keyboard shortcut is implemented in content" phrase. If the content implements a keyboard shortcut then the content author needs to attend to this SC, but if content is used by a person who is using AT that implements single-key shortcuts then it is not the responsibility of the content author (e.g. a web page that has headings conforms even though some screen readers/AT implement navigation quick keys to jump to headings).

Regarding the second part, we will update the Understanding text with additional examples and will consider adding an example for Alexa/Google Home - type systems. It is worth noting that the issue being addressed can arise with only one speaker in the room, as the speech recognition tools will process human speech and send a sequence of keystrokes through the keyboard interface and triggering a single key shortcut.

The WG decided on the above response, so we changed the text in the comment containing the proposed response to read "[Official WG Response]". Please confirm is you are satisfied with the response within 1 week. If we haven't heard a response in a week we will regard the resolution as satisfactory.
