screen: Redisplay

 
 11.7 Redisplay
 ==============
 
  -- Command: allpartial state
      (none)
      If set to on, only the current cursor line is refreshed on window
      change.  This affects all windows and is useful for slow terminal
      lines.  The previous setting of full/partial refresh for each
      window is restored with 'allpartial off'.  This is a global flag
      that immediately takes effect on all windows overriding the
      'partial' settings.  It does not change the default redraw behavior
      of newly created windows.
 
  -- Command: altscreen state
      (none)
      If set to on, "alternate screen" support is enabled in virtual
      terminals, just like in xterm.  Initial setting is 'off'.
 
  -- Command: partial state
      (none)
      Defines whether the display should be refreshed (as with
      'redisplay') after switching to the current window.  This command
      only affects the current window.  To immediately affect all windows
      use the 'allpartial' command.  Default is 'off', of course.  This
      default is fixed, as there is currently no 'defpartial' command.
 
  -- Command: redisplay
      ('C-a l', 'C-a C-l')
      Redisplay the current window.  Needed to get a full redisplay in
      partial redraw mode.
