There are many features and functionalities in the user interface of this publishing application that do not have any visual cues in the views where they are available, but they are all brought together in a "cheat sheet" view. It can be accessed by setting visible the button for it in the user settings, and which is then accessible immediately after logging in. User probably don't need that indefinitely, so there's no need to always be reminded of it.

As information in the "cheat sheets" there are brief explanations of the use of drag areas, mouse wheel, clicks and special keys, separate tools etc. Using them has a significant beneficial effect to the user experience.
