Folder action - copy selected items to clipboard

Newbie question;

I have modified the standard add new item alert script so that instead of a pop-up alert it sends a mail. But I would like to include the name of the added items in the mail.

I also wonder how I copy selected items (folders and files) to the clipboard. I have managed with one item, but I would like to do this with more than one item selected and without the whole path for the item.
