EXCEL Macro query

After assigning several macros to different buttons in EXCEL 2003, How can I identify which macro is assigned to which button.

Is this possible? – its certainly not straight forward with a right click or anything like that.

Is there a registry setting that hold this information?

I have recently acquired a database with a complex Macro that needs transferring to another PC but I need t identify what the macro is as it is only run through a click of a button and there are many macro buttons….!!

Thanks
