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.

Probably introduced at or before Emacs version 20.1.
