Some applications provide a "paste without formatting" that is distinct from "paste" but often that one removes things like hyperlinks, which you generally want to keep.

The "paste" idiom has been thoroughly stressed to the limit. Should "paste" paste just text? Should it include text color? Should it in crude text background color? Should it include typeface? Should it include text size? Should it include attached metadata like hyperlinks? Should it include other stuff around and peripheral to the text?
