Convert LISTNUM field codes to text

[remedios43]

Hi,

I am working on a document with about 100 examples numbered using LISTNUM fields. Is there a way to convert these fields to text once the document is finalised?
I want to keep the numbering but prevent any unexpected changes from happening (everytime I reopen the document, the arabic numbers go back to roman numbers, for instance).
I've tried the Ctrl/A Ctrl/Shift/F9 recommendation, but it doesn't seem to work in my version of Word (Word 2011 for Mac).
Many thanks in advance for your help,


E.
