Hey Andy,

Thanks for the reply.

That's actually not what I'm looking for.  That seems to scroll a
buffer for you according to a timed interval (probably for reading a
book or long document of some sort).  What I want is to force the
buffer to scroll when my cursor gets, say, 60% from the bottom.  Right
now, Emacs allows you to specify a minimum distance from the bottom
(usually 0) that the cursor should be before this auto-scroll happens
(and usually it centers the text vertically in the buffer, as though
C-l were pressed).  I'd like it to be dynamic.  So if I specify 50%,
and the buffer is 25 lines long, I'd like the buffer to auto-scroll by
one line whenever my cursor travels below 12 lines from the bottom.

Does that make more sense?
