What is orca
orca is:
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.
