Hi,
I was wondering what is the fastest and most reliable method to send data from a keyboard filter to a user app. I want to send the key pressed to a user app which will then process it. I believe that a PnP style notification is not possible on a filter, which would meet the fast & reliable requirements. Any ideas?

information to help you.
