Find and replace plain text with merge field in Word

I have an email template that currently has tokens like [[cost]]. However, I am now transitioning to using formal merge fields, which look like «cost».

I have the old format at lot in this template, so it is very inconvenient to manually copy-paste the new format. I tried using simple find and replace, but Word does not recognize the replacement text as a field.

How can I use find and replace or some similarly easy method to replace all occurrences of [[cost]] with a merge field?

Answer

Figured this one out pretty quickly!

Select the field and copy. Then, in the normal find and replace window, put ^c in the Replace with field.
