UndoRedoEnable: Boolean;
The UndoRedoEnable property determines whether it is possible to use undo and redo commands.
Use JSON or the setUndoRedoEnable method to set the property value and the getUndoRedoEnable method to get the property value.
If the property is set to True, undo and redo commands can be used, otherwise these commands cannot be used.
The example of use is given on the TabSheetSettings.EnableNativeContextMenu property description page.
