Superseded by AuthenticRange.IsDeleteEnabled
The IsDeleteEnabled property is now supported for any range of the document, not only the current UI selection.
// instead of:
// if (Application.ActiveDocument.DocEditView.IsEditClearEnabled)
// use now:
var objCurrSelection = Application.ActiveDocument.AuthenticView.Selection;
Declaration: IsEditClearEnabled as Boolean
True if EditClear is possible. See also Editing operations.
