> I have no idea what motivates the inclusion of functionality that manipulates the clipboard in the browser. I'm not sure, but I expect that it's the same sort of thing that motivates the inclusion of the ability to enable page content obfuscation schemes that -say- scramble a page's plaintext, but use CSS styles and JS voodoo to make it appear like the page contains only comprehensible text. I expect that -when using such a scheme-, you'd need to be able to modify what is being tossed on to the clipboard, as -I expect that- the inbuilt selection tool will pick up your garbage data as well as the intended text. [0] Edit: To be a little more practical, you could (for instance) use the ability to modify the contents of a clipboard to -say- create custom representations of your web application data formats and allow relatively easy transfer between instances of the software. [0] Yes, I do recognize that allowing copy and paste kinda defeats the purpose of this scheme, but the scheme is something that I've seen in the wild.
