Detect h RMB and click LMB ?

I was thinking...
since right mouse button (RMB) is no real use when clicked over a
google maps icon (overlay) - you just get Bookmark, Copy, Properties -
is it possible to change the functionality of the RMB ?
I would like to use RMB or something like that to "Zoom Through" a
region (eg do whatever it is I do when the user clicks "Zoom Through"
in the infowindow of this link:
http://www.evilc.com/phpbb/gmaps.php?action=seek&seekmode=location&location_id=2
)
So rather than the user having to click the Great Britain point and
select "Zoom Through" in the InfoWindow, I would like to be able to do
something like right-clicking the marker instead.
possible ?
