Mouse move on element
This is not possible.
I also disagree with highjacking the users mouse position, even if it were possible. If you did that to me as a user I would immediately leave your site.
JavaScript was designed this way on purpose. Imagine the internet as it is today with all the crappy sites and exploits out there, mix in the ability to control the users mouse and you have a much worse experience.
Let your users decided what they want to click on.
I think you can redraw the whole content of your web page so that the element you want get under the cursor. “ψ(`∇´)ψ
Another solution would be to move the window so that it gets where you want “ψ(`∇´)ψ
Javascript isn't able to move the mouse cursor -- it would be annoying as all get out if it could do this.
