Too easy to delete the wrong part

Just started playing this game for the first time and slowly getting used to it but i have found its too easy to delete the wrong part. I wanted to delete the path of the Resource Conveyor on a few occasions but ended up deleting the paint or fit body section.

hold shift and right click to only delete the resource conveyor.

I find this to be a problem on laptops like the Macbook where you can two finger click quite easily.
