Updating Cross references in Microsoft word

Question

Does anybody know how to update cross references in word. I am writing a report and have to provide references for the same. If I change the reference number how can I update it in entire document. For eg. If I have given reference number as [10] and if its updated to [11] how can I change it in entire document? Tried with select all text and updating fields, but its not solving the purpose....

Answer 1

Select the entire document by pressing CTRL+A, then press F9 to update all selected cross-reference fields.
