gnome-orca 2.22.1-0ubuntu1 (i386 binary) in ubuntu hardy

 A flexible, extensible, and powerful assistive technology that
 provides end-user access to applications and toolkits that support the
 AT-SPI (e.g., the GNOME desktop). With early input from and continued
 engagement with its end users, Orca has been designed and implemented
 by the Sun Microsystems, Inc., Accessibility Program Office.
 .
 Orca defines a set of default behaviors (reactions to application events) and
 key bindings (reaction to user key presses). These default behaviors and key
 bindings can be overwritten on a per-application basis. Orca creates a script
 object for each running application, which merges both the default behaviors
 and key bindings, and the application specific ones. Orca provides the
 infrastructure to activate and deactivate scripts, as well as a host of
 services accessible from within the scripts.
 .
 Note: gnome-orca works without gnome-mag, you just need it for magnification.
