I the NEK manual I read: “To move or copy notes in the editor … you use the same methods as in te key editor”. No big issue, but incorrrect and sometimes very irritating since there is no keyboard shortcut change possible. All over Cubase/Nuendo the ‘ALT’ key means ‘copy’. Only in the drum editor (from Cubase4/Nuendo4 on) it means a new note is added. When you want to duplicate a note in the drum editor you need to use SHIFT+ALT. Am I the only one using the drum editor!?
I hope this will be added to the wish/bug list…
