In network protocols, messages are often confirmed by the receiver. In order to model such protocols effectively, it would be nice to define a set of replies (either with constant text or a using some sort of patterns), assign them to some shortcuts (which can ideally be fired just by left hand) and then, when a message is selected and a shortcut is pressed, the defined reply would be generated right after the selected message, having the selection changed to this generated reply. The function should also be accessible via the SCStudio menu.
