UserInterface.markingMenuDisplaying Event

The markingMenuDisplaying event fires just before the marking menu and context menus are displayed. The marking menu is the round menu displayed when the user right-clicks the mouse within Fusion. The context menu is the vertical menu displayed. The event provides both the marking menu and the context menu so you can examine and edit the contents of either one or both of them before they are displayed. Fusion will then display the marking and context menu that you've customized. If either one is empty it will not be displayed.
