Comment 3 for bug 752503

I forgot wrote the bug triaging steps:
1. Please you launch Natty live CD for access=v2, v3 or braille mode.
Access=v3 is screen reader mode.
2. When Orca Screen Reader is started, click the help button.
3. Try moving for example the main index help page with Up or Down arrow
key. Because caret navigation is not enabled by default for Webkit GTK
based Yelp, you will be not hear any actual highligted line.
