orca binary package in Ubuntu Jammy s390x

 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).
 .
 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.
