-@vindex automatic-hscroll-margin
- The value of the variable @code{automatic-hscroll-margin} controls
-how close to the window's edges point is allowed to get before the
-window will be automatically scrolled. It is measured in columns.
-If the value is 5, then moving point within 5 columns of the edge
-causes horizontal scrolling away from that edge.

-@vindex automatic-hscroll-step
- The variable @code{automatic-hscroll-step} determines how many
-columns to scroll the window when point gets too close to the edge.
-If it's zero, horizontal scrolling centers point horizontally within
-the window. If it's a positive integer, it specifies the number of
