Thanks for pointing that out.

I got Space for scrolling down and Delete for scrolling up  
incorporated inside my DNA, from years of occasional OzTeX use (I  
think it comes from xdvi, doesn't it?). It was practical to see Space  
have the same effect in a number of other viewing applications, but I  
couldn't find any equivalent to Delete. Now I know: that's Shift-Space.

I do agree with one comment made in another message from this thread:  
having to remember the different Alt-Ctrl-Shift-Cmd-Arrow  
combinations in Textures, TeXShop, Preview, Adobe Reader, etc. (of  
course they are different in each) is irritating and a waste of time  
and energy.

On the other hand, even if they are not quite conformable to Apple's  
HIG (and Apple's has had a long record of forgetting about these HIG  
when they find it convenient), one-key scrolling actions are  
definitely useful IMHO. When you try to save a few trees and re-read  
and edit a long document on screen, being able to scroll fast, easily  
and with minimal keystrokes is a time-saver.

Regarding PDFKit, as far as I remember I read somewhere that in  
Leopard it has been moved out of CoreGraphics, allowing the  
developers to bring in some significant changes (including better PDF  
support). Accordingly, I imagine what we see now in Tiger or Panther  
may be significantly different from what we'll see in Leopard in a  
few months' time.
