Abstract
Few users ever attain mastery with an application. Mastery, the state of knowing how to work efficiently with an application requires an understanding of the underlying conceptual model of the system. The active user paradox is one of the main inhibitors of mastery. In this study, we present HotKeyCoach, a training method designed to insert into the flow of the activity learning events that provide contextually relevant training and help the user to circumvent the active user paradox in the pursuit of application mastery.
