Shortcodes in Revise app are a special syntax that allows you to reference values of fields of an entry that is currently being edited.

The syntax for the shortcodes is as follows: {fields.FIELD_NAME.LOCALE}. fields is a static part and never changes. FIELD_NAME is an id of the field of the content type. You can find the id in the Content model overview inside Contentful. LOCALE, as the name suggest, is the locale code of a locale to which you want to refer (for example en-US).

Shortcodes are useful in many situations. You would use them when changing content type id, content type field id, or when migrating between field types (for example between single- and multi-reference fields).
