Hi Darragh,
Finally, I have a request: I would really love it if I could tell Orca to skip the message header information such as from, to, subject etc and start reading the message. I find it a bit annoying at the moment and although it could be my lack of experience with the graphical interface, I find that the results when pressing F6 to jump to the preview pane can be somewhat inconsistent. Example, Sometimes it's at the top of the message header but other times it's half way down.
We (the Orca team) discussed this yesterday evening. It's a good idea. If I remember correctly, the consensus was to have a special "hot key" in the Evolution script, that would take you to the start of the actual message (so we didn't have to keep tabbing and arrowing over the message headers. I've opened up bug #422487 on this. http://bugzilla.gnome.org/show_bug.cgi?id=422487 Please add further thoughts and comments there. Thanks.
