Hi
Welcome to Microsoft Q&A!
Narrator
is a screen-reading application that's built into Windows 11. Its gesture operations are managed by the system.
Microsoft UI Automation is an accessibility framework that enables Windows applications to provide and consume programmatic information about user interfaces (UIs). UI automation is primarily used to interact with the UI elements of an application.
UI Automation doesn't handle the Narrator's gesture operations directly.
If you want to handle Narrator's gestures via UI automation, you could try to do this by simulating keyboard or mouse actions.
Thank you
