Common|CustomFields|...
This key can hold the settings for one custom field. The registry key name can be identical to the actual field name but it need not be identical. If both names are different, the actual field name must be given in the parameter "FieldName" within this key, otherwise the parameter "FieldName" is obsolete. The format for the field name can either follow the syntax for database fields (two parts, separated with a slash) or the syntax for BroadcastSystem (two parts, separated with a dot). Arbitrary usage of upper/lower case letters is possible, because the comparison for field names is always case-insensitive.
