Workbook events occur within a particular workbook. Many workbook events occur because something happened to an object in the workbook, such as a worksheet — any worksheet — that was activated, or a cell — any cell — that was changed. Other workbook events occur because the workbook was imposed upon to do something, such as to open or close, or to be saved or printed.
