Thank you very much!  That is very helpful information.
One of the problems with googling is a lot of the stuff I turn
up is outdated or wrong (maybe because Gnome/gtk changes with
every release).

I've looked at xfce-look.org before but it is pretty hard to grok
behavior from a few screen shots and a long flat list of choices
is not all that helpful.  I'll spend more time there and see if I 
can find something.

I see what you mean about the slow steppers.  In part that seems
to be due to it scrolling only about 1/2 a line at a time.  I don't
suppose there is a setting somewhere that controls the number of 
pixels that each stepper click scrolls by?  Or more directly, the
repeat time interval when then the mouse button is held down?

Anyway, you gave me a good start though it looks like I'm not going 
be able to avoid learning a lot more about customizing gtk.
