How to copy past in the score with Cubase 12 Pro

I am using Cubase 12 Pro and I don’t know why I am not able to copy past on the cursor position in the score editor, like I could be able to do it in the past, with Cubase 5 VST Score (23 years ago… :smiley: )

Also, if I need to copy a full section (multiple tracks for multiple instruments) and past them in another bar, for the same section of instruments (or maybe another section of other instruments, different tracks), is it possible to do it with Cubase 12 Pro? Or am I obliged to do it track by track?

Of course you can still copy/paste events in the Score Editor.
You would have to provide more details.

And yes, you can copy and paste multiple staves at a time.
