# $EPIC: scroll_backward,v 1.2 2005/03/08 05:53:31 jnelson Exp $
Synopsis:
   window scroll_backward

Description:
   This operation moves the scrollback view backwards (towards older output).
   The amount it moves is determined by WINDOW(4) SCROLLBACK_RATIO,
   which is a percentage of the window's size.  It is usual and customary 
   when you scroll backward for the scrollback view to become the current
   view, so you will always see an immediate effect.

   When you reach the top of the scrollback buffer, further attempts to go
   backward will result in a beep.

   When the scrollback view is active (after you use scroll_backward), new
   output to your window is buffered (held) without bounds, so you will
   never lose any output.  But it will use more memory.

   You may want to read the WINDOW(4) help file discussion about views.
