Provide a documentation for JavaScript (from MDC, for example)

How about using http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide and http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference documentation by IDEA to display when Ctrl+Q is pressed for JS code ?

IDEA already knows to auto-complete a JS code, adding a documentation to it would be terrific, I suppose.
