Returns the vertical coordinate of the event within the screen as a whole..
Syntax
yCoord = event.screenY
Parameters
yCoord is the offset from the top of the screen in pixels.
Example
function checkClickMap(e) {

Notes
When you trap events on the window, document, or other roomy elements, you can get the coordinates of that event (e.g., a click) and route it properly, as the "clickMap" example demonstrates.
