KeyboardDeliveryInterceptor Class

  • Reference

Definition

Namespace:
Windows.UI.Input
Edit

Enables an app to override the system processing of raw keyboard input, including key combinations such as shortcut keys, access keys (or hot keys), accelerator keys, and application keys.

The raw keyboard input is intercepted, suppressed, and routed to the app (when in the foreground) for processing.

Note

Secure attention sequence (SAS) key combinations, including Ctrl-Alt-Del and Windows-L, continue to be processed by the system.
