gnome-orca 0.2.2-0ubuntu1 (sparc binary) in ubuntu dapper

 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.
