screen: Scrollback

 
 12.1.2 Scrollback
 -----------------
 
 To access and use the contents in the scrollback buffer, use the 'copy'
 command.  SeeCopy.
  -- Command: defscrollback num
      (none)
      Same as the 'scrollback' command except that the default setting
      for new windows is changed.  Defaults to 100.
 
  -- Command: scrollback num
      (none)
      Set the size of the scrollback buffer for the current window to NUM
      lines.  The default scrollback is 100 lines.  Use 'info' to view
      the current setting.
 
  -- Command: compacthist [state]
      (none)
      This tells screen whether to suppress trailing blank lines when
      scrolling up text into the history buffer.  Turn compacting 'on' to
      hold more useful lines in your scrollback buffer.
