Synopsis:
   set scroll_lines [<number>]

Description:
   This setting offers a compromise of sorts between the available modes
   of the SCROLL variable.  When the last line of the display contains
   text, the client will scroll all text upward by the number of lines
   specified.  The normal behavior uses a setting of 1 (one).  If it is
   set to 0 (zero), the client automatically turns SCROLL off, and it
   must be manually enabled again to turn scrolling back on.
