Thanks to everyone for their comments, and esp. to Richard for opening my eyes! I had always entered a note then pressed up and down arrows 7 times, follwed by control and enter. I tried what you said (enter, control plus ONE up or down key) and hey presto - did the trick! Much easier! As pleased as I was, I was also a bit peeved! I thought "I've had NWC for 5 years and how come I've not been aware of this feature? How come I missed that? Where on earth do they tell you about that?" Then I opened up all the menus and saw the "Chord Member" phrase - the penny dropped! I don't know why I'd always ignored that before - possibly because the name is a bit misleading? Perhaps if it had been called "Chord Octave", I would have cottoned on sooner! Anyway, thanks again!
.... is entering (2-note) octaves! How I despair! It sometimes seems to be the action I do the most per piece. I wish one could enter a single note, then highlight it with one of 2 short-cut keys that automatically added the same note (of the same duration) either 8 notes up or 8 notes down. It would be a lot more useful than some of the obscure features they put in. Anyone agree?
