OnCommandFinger is a TIdFingerGetEvent property that represents the event handler triggered when a threaded client connection makes a Finger request. 

OnCommandFinger expects an AUserName argument that is the query the client is making. This event does not occur in the main program thread but in the content specified for the client connection. 

OnCommandFinger is used during execution of the threaded client, and allows the server to implement resolution of the Finger query. Applications must assign a procedure to the event handler to allow responding to the event notification. The event handler should be used to locate user information for the Finger query, and write any reponse or error messages to the client connection in AThread. 

Use OnCommandVerboseFinger to resolve Finger queries that require verbose output.
