{-String.Replace-|-that is my text to replace-|-is-|-was-}
This changes "that is my text to replace" into "that was my text to replace"
So if you pull out your text out of a previous macro, then it should be something like this:
{-String.Replace-|-{-FieldData.FieldData-|-●2●7●8●2●9●3●-|-≡8≡4≡9≡3≡3≡9≡7≡6≡4≡-}-|-is-|-was-}
