Screen readers

Niri has basic support for screen readers (specifically, Orca). We implement the org.freedesktop.a11y.KeyboardMonitor D-Bus interface for Orca to listen and grab keyboard keys, and we expose the main niri UI elements via AccessKit.

Make sure Xwayland works, then run orca. The default config binds SuperAltS to toggle Orca, which is the standard key binding.

If you're shipping niri and would like to make it work better for screen readers out of the box, consider the following changes to the default niri config:

• Change the default terminal from Alacritty to one that supports screen readers. For example, GNOME Console or GNOME Terminal should work well.
• Change the default application launcher and screen locker to ones that support screen readers. Suggestions welcome! Likely, something GTK-based will work fine.
• Add some spawn-at-startup command that plays a sound which will indicate to users that niri has finished loading.
• Add spawn-at-startup "orca" to run Orca automatically at niri startup.

Desktop zoom

There's no built-in zoom yet, but you can use third-party utilities like wooz.
