I have seen a few threads explaining that Flash can be used to set the clipboard data in Mozilla and Internet Explorer, it's easy, etc.
For example http://stackoverflow.com/questions/316508/greasemonkey-javascript-copy-to-clipboard-button
However, I would like to read the clipboard and remove certain items before setting it. Is there any way to do this?
So.. Is it possible then to detect whether copying and pasting is occuring? Then redirect them to another URL?
