Fedora for user gdm had an audio permission issue; however, it has
reportedly been fixed.  Perhaps someone could test this?

I suggest someone try to create a GNOME, GDM, and KDE accessibility
keywoard shortcuts/gestures, then get concensus.  I would not worry
about Windows...

Perhaps someone could start a wiki at http://live.gnome.org/GAP/gestures
and create three columns of what to start which which gestures.  For
example:

=================================================
Action               GNOME      GDM*     KDE
=================================================
gnome-at-visual
gnome-at-mobility
-------------------------------------------------
*global settings for user GDM.

I had opened a similar bug back in 2006.  However, with the new
"gnome-at-visual" and "gnome-at-mobility" commands, then they should be
started instead of directly invoking the ATs.
gnome-default-applications-properties should be used to determine what
is run by those two commands.
