¿Aprobar publicación directamente desde el modo de vista previa?

¿Cómo apruebo una publicación directamente desde el modo de vista previa, en lugar de tener que volver al modo de edición y / o al modo "lista de publicaciones"?

Estoy cargando varias publicaciones (cientos) de forma secuencial, pero quiero verlas en vivo brevemente antes de la aprobación.

Aquí hay algo que tengo por ahí:

No lo he probado en mucho tiempo, pero debería funcionar bien.

¿Qué pasó con solo CTRL-clic en el botón "Vista previa" para obtener la vista previa en otra ventana / pestaña de su navegador? Luego solo presione CTRL-W para cerrar la pestaña de vista previa y luego presione el botón Publicar.

De acuerdo, la solución de baja tecnología, y la solución de Bainternet definitivamente es genial. Solo pensé en ponerlo ahí fuera ...
