After inspect in the meta-menu, Jinx shows the main-menu. It presents commands which operate on the current database on a record-by-record basis. The data part of the screen will show (part of) the current record, one field per line. When you have `long' fields that don't fit on the screen, you can move the view on the record to the right (left) with ⇒ ( ⇐).
You can move to the next (previous) record with prev (next). The current field is indicated by a `>' in the first column. Move to the next (previous) field with ⇓ (⇑).
