Is It possible to copy/paste something from a map to another?

No, you can't. You can copy the map file however.

I don't recommend to copy someones map. It is more fun to make your own map and it also gives a better experience for the player.

Don't worry, it's just that I want to re-use some parts of other levels from my custom story for the player to be lost

You can by exporting it and then you import it to your map

Thanks a lot, it works!
