Accessing clipboard from browser via JavaScript

Hi,

I'm looking for a way to mark several input fields on a webpage by mouse and copy the input fields' content to clipboard. Is this possible at all? The only usable technique I have in mind is JavaScript, but I don't know if can access the operating system's clipboard from within a browser. Any ideas or hints are appreciated.

In the old days you were able to do this, but with today's security minded folks, it is not possible without browser settings to be changed.

People who do it use Flash [http://code.google.com/p/zeroclipboard/], but Flash is starting to restrict it too.
