I've posted the same instructions literally thousands of times. You're one of a very few (probably less than five in the past 15 years) who's ever come back claiming to not understand something so simple.

Which parts of:
The field brace pairs (i.e. '{ }') for the above example are all created in the document itself, via Ctrl-F9 (Cmd-F9 on a Mac)
and:
you can't type or copy & paste the chevrons (i.e. '« »') - they're part of the actual mergefields, which you can insert from the 'Insert Merge Field' dropdown
don't you understand?
