Control brings up a context menu here. Tried all other modifiers as  
well. Sure this isn't a 3rd party extension?

Tell me about it, under Panther I was using uControl which gave a  
virtual scroll wheel (by holding down ctrl-option and moving the  
mouse), unfortunately that kernel-ext. broke with the release of  
Tiger, and it took a long time to get rid of the habbit, especially  
since uControl also simulated a horizontal scroll wheel (which turns  
out to be much more useful than vertical scrolling, since many  
applications neglect to map keys to horizontal scrolling).

As for trackpad, doesn't Apple support scroll wheel simulation when  
using both fingers on the trackpad and moving these up/down (I think  
it needs to be enabled, don't have a trackpad myself)?

I'd prefer it as a system-wide patch (was hoping that uControl could  
got updated to Tiger).

Personally though, I scroll using cmd-option-ctrl cursor keys in  
TextMate (which scroll the buffer w/o moving the caret). Of course  
conformance between apps would be desired.

I have this in my DefaultKeybinding.dict [1]:

     "^~@\UF700" = "scrollLineUp:";
     "^~@\UF701" = "scrollLineDown:";
     "^~@\UF702" = "scrollColumnLeft:";
     "^~@\UF703" = "scrollColumnRight:";

So it also works in Mail etc.
