You mean, you'd like the doc string to mention the names of functions
affected by this variable?

> For example, what's the difference setting it to 1, 100, 10000?

If you set it to 10000, then moving point 10000 lines below the lowest
screen edge will scroll so as to bring the point's line to the last
line of the window.  If you move more than 10000 lines, the point's
line will be centered (by default, unless you also change
scroll-*-aggressively).
