GNOME 48 Accessibility Improvements: AccessKit, Orca Shortcuts, and More

GNOME 48 boasts significant accessibility advancements. GTK 4.18 integrates the AccessKit backend, enabling accessible GTK applications on Windows and macOS for the first time. Wayland support for Orca screen reader keyboard shortcuts is complete, closing a major accessibility gap. Furthermore, WebKitGTK accessibility has been improved, making GNOME Web a fully accessible, sandboxed browser. The new accessibility tool, Elevado, is also released, offering developers a new way to explore and inspect application accessibility features. Numerous smaller improvements enhance accessibility in GTK and related libraries, including enhancements to the file chooser, list boxes, button size detection, and text attribute reporting.
