Key Editor Copy & Paste Question

I want to create some midi harmonies in the key editor.
After selecting some notes in midi key editor how do I copy and paste these notes a few semitones higher or lower vertically and keep my originally selected notes in their original position.
I can copy and paste horizontally
Also I know If I select a note and hold shift and hit up arrow this moves the note up a octave.
How do I cope and paste vertically
Many thanks.

Watch the chapter of this video. It will explain moving and then copying.

Thanks Johnny, I like Dom he’s too talented and clever :clap::clap::clap:
