Clearing out entries in a keyword field

Due to a workflow error I have many records in a file cabinet with an incorrect entry in a Keyword field. I would like to clear these entries using AutoIndex, but if I write a new value into a Keyword field it is simply added. The original entry remains.

Does anyone know of a way to remove or change and entry in a Keyword field using AutoIndex?

Any clues appreciated,
