Events are used to detect that something happened, not to cause the thing
to happen.  The copy event tells you that a copy happened, you don't
dispatch "copy" to cause a copy to happen.  You use regular API calls to do
that, like execCommand("copy").  You're correct that you usually can't use
that except in response to a user action, of course.
