+### Nieuw

+- **Sneltoets voor het klembord.** In de tab **Sneltoetsen** kun je een combinatie zetten op **Vanaf klembord**. Die opent de afbeelding op het klembord in de editor. Standaard is er geen sneltoets. De gekozen combinatie staat ook bij **Bewerken vanaf klembord** in het systeemvakmenu.
+- **Afbeelding naar de editor slepen.** Sleep een afbeeldingsbestand, of een afbeelding uit een ander programma, naar het kniip-venster. kniip vraagt daarna of je die afbeelding wilt openen, zodat een lopende bewerking niet zomaar verdwijnt.
