The first question that must be answered is:  What are you pasting in to?

I say that because if, for instance, you're pasting into Notepad you simply cannot retain the formatting under any circumstances.  It is a text editor and anything pasted into it will retain the text only.

If you're pasting into, say, Microsoft Word, what controls the retention of formatting is a combination of what you have set as your default paste behavior, or using the post-paste button that shows up to override that behavior when you need to do so.
