Voice recognition
Some links within a forum are not underlined and so may not appear to be links, but it is possible to open a discussion by saying its name.
Some Dragon users may find that even if a button is visible on screen, it may be invisible to Dragon. Scrolling the page slightly (even just one "Press down arrow" command) can bring the button into view for Dragon.
To access any element that does not respond to direct voice commands, it should be possible to use "Mousegrid", "Press tab key" or "Press enter" commands.
