MainRVAControlPanel Global Variable
The main control panel for RichViewActions.
var MainRVAControlPanel: TRVAControlPanel;
If no other control panels are created, this variable returns a default control panel object (not belonging to any form or datamodule).
If an application contains a single TRVControlPanel on a form, it becomes the main control panel automatically, and MainRVAControlPanel returns this control panel.
Another control panel can be made a main one if you call its Activate method.
