"Paste" command in search box contextual menu

At the moment the search box has a contextual menu but its purpose is only to refine the scope of a search. I sometimes miss the availability of a "paste" command to paste a term to search for, in the same menu or maybe in a separate menu. In a whole mouse oriented scenario we may for example click and highlight a word in our browser, copy the word from the contextual menu of the browser and then we can't paste that word in CN to search for it, we have Ctrl+V but it requires the use of the keyboard. I would see this as a small but useful usability enhancement.
