How do I copy event sheets to another project?

I want to copy a complete event sheet over to another project. I know that the core information that is referenced has to be the same: variables, objects, behaviors etc. . I want to avoid redoing everything, so how do I merge the compatible projects?

This question would also apply to layouts.

Copy any referenced objects first. Copy any referenced globals. Copy the events. It might take a few tries to catch everything, but it can be done - I've done it several times.

Thank you.

I don't know why I couldn't figure that out. I guess I was expecting the entire sheet to be copied instead of piece by piece, but it makes sense now.
