Slur starting from the lower staff to the upper staff


I try to continue a slur starting from the end of a lower piano staff to the start of a new upper staff system as the picture. I had a look to the properties panel in order to activate the down/up direction but without success. Thanks, Sébastien

Select the starting note, ctrl-click the end note, S (for slur).

Thanks @Janus. Is it possible without keyboard?

See selecting in the User Guide for iPad.
