The tip show you how can make a hook for keyboard .
The hook will detect when the user press a key ( in your case choise action just for enter key ) and send ( I don't know how you communicate between client and server ) then the message .

I think you know how to send the message . If not I can send you a project to see how can send messages between server and client ( is a chat project ) .
