When in the recording mode, the mouseover event
prompt up the HTML content of the current element.

This is actually not enough.
It would be nice if the HTML display of the current
element could be changed in order to highlight the
element currently being focused on.

For TextBox, it would mean setting the backcolor to
green, for TABLE elements, it would mean setting all the
TR TD elements backcolor to green, etc...
The effect should be disabled as soon as the mouse
leaves the current element.
