It is not possible to unset { -brand-short-name } as the default client within { -brand-short-name }. To make another application the default you must use its 'Set as default' dialog.
Nun ye dable desaniciar { -brand-short-name } como veceru predetermináu dende'l propiu { -brand-short-name }. Pa que otra aplicación seya la predeterminada, tienes d'usar el diálogu 'Afitar como predeterminada'.
