I often debug my javascript code using the Chrome web debugger. In the elements tab, hovering over an element show a tooltip with a few pieces of information, including the width and the height of that element.
Sometimes, I need to see the page coordinates of the current mouse position. But it seems the debugger does not display this kind of information.
So, is there a way to add it? Like an extension or maybe there are other options?

Using the accepted answer I could add the following bookmarklet and have exactly what I wanted:
javascript:document.onmousemove = function(e){var x = e.pageX;var y = e.pageY;e.target.title = "X is "+x+" and Y is "+y;};
