I would like to remove this tags:
SCRIPT
MusicBrainz Album Release Country
MusicBrainz Album Status
Media Type
They will not removed using the additional $keep-function.

My attempts with versions like
$set(%script%,)
or
$set(script,)
or
$set(media,)
or
$unset(media)
doesn’t work.
Other unwanted tags will be removed with the above $keep-function.

Could please someone tell me the working syntax to remove this tags?

Do we have an overview other then this and this with a complete list of working tags and how they can be removed in Picard?
