Well, I don't want to be negative but, AFAIK, Opera is pretty
restrictive in terms of changing system events. Try disabling right
click and you'll know what I mean... :-|

IMO maybe the best solution will be changing the interaction so that
only primary button press (usually left click) is used - this will be
quite universal and will be prepared for somehow different
interactivity paradigms (such as PDA or touch-sensitive displays).
You'll probably need some menu or similar to display the list of
possible actions (instead of using different modifiers). ;-)

If you really want to disable the zoom behavior, you might go along
with it by doing trickery like implementation detection (so this works
in other browsers than Opera) combined with an inverted transform of
the zoom (transform the document while zooming in/out). It's somehow
ugly bug it will likely work. :-)

Finally, I haven't yet got a clear position on Opera's behavior
regarding the event handling restrictions: although I agree that it is
limiting from an author point of view, it also protects users. After
all, I also hate when Web sites display the "Right click disabled"
warnings and/or try to mess with basic interaction paradigms...

Hope this helps,
