Deleting a scene without affecting keyframes in the next

Hello.
I am using Fusion for my first motion graphics video. I have a fairly simple video but with a significant number of nodes and animations. How can I delete/shorten/extend scenes without affecting animations and keyframes in scenes which follow?
For example I have 20 merge nodes. I would like to shorten merge number 2. But if I just shorten the merge everything else stays at the one place as before cut and therefore I will have a empty part of the video which I need to get rid of.
Thanks, hopefully it is understandable
