I have just started playing Planet Coaster and I have noticed in some YouTube videos that the player is able to duplicate a group of objects but I am unable to figure out from the videos how they do it - they must be using some hotkey I think.
For example, I see people surrounding trees with submerged rocks (= with just the tips of them above ground level) in a circular fashion to make some stone border around it. They do this by placing two rocks that are on the opposing edges of the circle then clone the them both, and rotate the clone around the centroid which makes the whole process faster.
I am aware that there is a 'Duplicate` button at the top-right corner of the screen when an object is selected but for some reason, when I have more than 1 object selected, it just disappears, I can only see move/edit/advanced edit/destroy buttons.
How can I do this?
