Highlight the item(s) in the finder and then select "Create Archive of xxx" from the File(?) menu... you can also get to it from the "cog" menu in any Finder window. I'm going from memeory, so I might be a little off here...How the heck do you do that?? I know how to do the PDFs but not zips.
Edit: looks like that feature came in with 10.3
