Typically you'll get a selection object, get the range object, and .execCommand("Copy") on it. Unfortunately it only really works in IE (afaik); it used to work in FF if you got the Allow Clipboard Access plugin, but even that's been disabled.
It could potentially be a huge security risk, which is why it's had to be sandboxed into plugins like flash.
Why is copying data into the clipboard a security risk?

But it's already in a sandbox (the browser). Why do we need a sandbox inside the sandbox?
I really don't understand what the huge deal is with this. It's almost harder to get some plain text onto the clipboard than it is to get the user to run a .exe.
