You don't know where you want to paste it? How would we know? Where do you
want it to go, whatever it is? Into an e-mail? Into a document? Where are
you copying from?
I'm looking at your vaguely worded and poorly spelled question and I'm
going to take a guess at what you mean.
You know how to copy the text from a web page, but you don't know how to
copy the HTML formatting and/or you don't know how to copy the graphic
elements on the page.
If that's correct, reply to this post and - in complete sentences with
reasonably correct English - explain exactly what you are copying and
where you want to paste.
