+# $EPIC: bind_scroll_backward.txt,v 1.3 2008/07/28 05:15:51 jnelson Exp $
+======Synopsis:======
+[[bind]] <key> scroll_backward
+======Description:======
+This executes the [[WINDOW]] [[window SCROLL_BACKWARD|SCROLL_BACKWARD]]
+command.
+It moves the scrollback view backward, towards older output.
+The amount it moves is determined by [[set scrollback_ratio]] as a percentage.
+It is normal for the client to switch to the scrollback view when you scroll
+back, so you should immediately see an effect.
+When you reach reach the start of the scrollback buffer, further attempts
+to go backward will beep, and the scrollback will not change.
+Whenever the scrollback view is active, new output to your window is buffered
+("held") without limit, so you will never lose any output.  A common cause of
+high memory usage is a window on a busy channel being stuck in scrollback mode
+and then forgotten.  Since the scrollback is never trimmed, it grows without
+limit, which can use up a lot of memory quickly.  You can use the %K status
+bar expando to tell you when a window is using the scrollback view.
