Shows/hides "smart popup" button for the current (at the position of caret) item.
property SmartPopupVisible: Boolean;
(introduced in version 10)
The editor hides this button automatically on document change or clearing.
Since smart popup works only for the current item, you must ensure that it is displayed for the current item: update it in OnCaretMove event. Even if this property is True, reassigning True to it makes sense, because it links the smart popup to the current item.
Properties for the button are defined in SmartPopupProperties.
