Octopus - legato switch?

[stimresp]

Hi,

I just aquired Octopus and all is going great except...how do I activate legato?

It's referenced in the manual as a switch but I can't find it on the interface. Am I missing something obvious?

Thanks in advance for any help.

"Porta" or Protamento is Legato, sorry for the synonym, not well done
