Editor's Notes

  • #2: We hebben dit sjabloon zo ontworpen dat elk lid van het projectteam beschikt over een set dia's met een eigen thema, waarmee dit lid zijn of haar onderzoek kan presenteren. Leden kunnen als volgt een nieuwe dia aan alleen hun eigen set toevoegen: Markeer de plek waar u de dia wilt toevoegen: Selecteer een bestaande dia in het deelvenster met miniaturen, klik op de knop Nieuwe dia en kies vervolgens een indeling. De nieuwe dia krijgt hetzelfde thema als de vorige die u hebt geselecteerd. Maar wees voorzichtig! Voorkom dat u per ongeluk de thema's van uw medeteamleden verandert. Dat kan gebeuren als u een themavariant kiest op het tabblad Ontwerpen, waardoor alle dia's in uw presentatie worden gewijzigd in het gekozen thema.
