RockScroll does not work with VS2010. The last thing I checked was that the VS-gallery had several somewhat similar extensions, although I do not know if any work with VS2010 and the new editor. I know that in MS, several people from VS are working on a new VSIX, like RockScroll, during their free time, for possible inclusion in a future version of Pro Power Tools, although I have not heard anything about this in the last couple of months.
