I used to use the #BrowserNav #Addon for #NVDASr. Not sure why I stopped, but I remember having to unset the CTRL+j hotkey *every* time because it conflicted with accessing the browser downloads.

There was an update recently so I am re-trying it, only to find that the say line command is now replaced with a "No URL" error message.
I wish there was a better mechanism for developers to see what keys are in use. I know it's silly to expect everyone to be on a laptop layout and to regularly use the same keys I do. Just a shame there's no easy way of avoiding these conflicts.
