This function registers the onkeydown event on the popup (ie, a div that has the classname keyFormWrapper)
When 'Enter' key is pressed, it finds a link which has class name 'ajaxSubmit' inside that keyFormWrapper popup
and simulate click event on it. If you have more than one links with that class name in the popup then
there is problem. You must use some resolution strategy to select the proper one. Currently it is 
selecting the first one.
