I don't agree that's so linear but ok, lets be precise then
- yes you act on the browser contents
- the action is "increase fonts"
- you got a (+) for increasing fonts

Where should the wheel move?

So in kghostview, for instance, you have plenty of ways to do zoom in, one of 
them beeing pressing the (+) button, the moushweel will do exactly the same 
as all of those above (that is, "zoom in"), but we should abstain from 
relating it to "zoom in"?

I'd prefeer someone to flip a coin to chose the behaviour than having this 
kind of feature configurable.
