Copy a Family to a new project?

Is there a simple way to copy a family from one project to another?

For instance, if I create a family that handles advanced particle behavior, can I later copy it into another project?

The only way I know of at the moment is to, in the new project, exactly replicate the family with all the instance variables, effects, and behaviors by hand, and then copy the relevant event code, first by copying top level event sheet variables into a new events sheet, and then copying all the other events over, so as to avoid the missing variables error message.

Currently I save most of my projects as single files, but I'm curious if it might be possible to copy families and other objects between projects by just dragging and dropping files between project folder structures, or maybe copying blocks of xml or something.

Any advice or suggestions much appreciated.

Yes I am curious about this as well if anyone has an answer or tutorial to point me towards. I am trying to merge some things from the examples into my little game, but they will not go through clipboard. What am I missing?

I think the answer to Fisholiths question will help me as well.

Well I finally got got some objects to go between the two projects using my clipboard. I think maybe I was grabbing too many at once or maybe there is something wrong with my clipboard...So I am in better shape, but if someone answers Fisholiths question I will be all ears as well.

Thanks,
