Highlight list line on hover?

Hi Craig,
By mouse hover, I mean equivalent to the html/CSS mouseover http://en.wikipedia.org/wiki/Mouseover. 
So, the requirement is for each line in a list field to automatically toggle its highlight to true as the mouse enters the line's UI area (perhaps a virtual 'rect') and false as the mouse leaves - all without any clicking. Klaus' script achieves this for a list field. 

I just retried both John's and your scripts, to see if it was me... 
• John's does not affect the default list field behaviour - the highlight changes only on mouseDown.
• Yours throws an error (which I didn't notice before, because I had other errors in the script) - on the second line, no target found

Maybe it's the use of the 'select' keyword, as according to the dictionary, this is used "to select an area of an image"?
