        - Identifying items (see below)

        - Identifying items, or picking them up for the first time (see below)

        When an item is identified, it will be noted if it is an 
        artefact
        (fixed, unrand, or random) or if its short description matches a 
        regex. E.g.

        When an item is identified or picked up for the first time, it will
        be noted if its short description matches a regex. E.g.

        Artefacts (fixed, unrand, or random) will always be noted when
        identified, regardless of note_items.

        The description matched against has the same prefixes as notes
        for the menu_colour option (e.g., "identified", "know", etc).
