(setq scroll-conservatively 101)

以下是*Help*生成的describe-variable窗口中的信息：

scroll-conservatively is a variable defined in `C source code'.
Its value is 101
Original value was 0

Documentation:
Scroll up to this many lines, to bring point back on screen.
If point moves off-screen, redisplay will scroll by up to
‘scroll-conservatively’ lines in order to bring point just barely
onto the screen again.  If that cannot be done, then redisplay
recenters point as usual.

If the value is greater than 100, redisplay will never recenter point,
but will always scroll just enough text to bring point into view, even
if you move far away.

A value of zero means always recenter point if it moves off screen.

You can customize this variable.
