ThisWorkbook and the worksheet modules are used for event procedures.
See:

They may also be used for custom workbook- and worksheet-level
properties and methods. I know Chip and others prefer to reserve them
for events but for me they better fit the OOP approach. I never use
public variables so a public property in the ThisWorkbook is useful
for implementing a global. And I will only put code in a standard
module if there is no alternative e.g. need to call a procedure using
its address in memory.
