Refreshing the Screen
=====================

   The function `redraw-frame' redisplays the entire contents of a
given frame (Note: Frames).

 - Function: redraw-frame frame
     This function clears and redisplays frame FRAME.

   Even more powerful is `redraw-display':

 - Command: redraw-display
     This function clears and redisplays all visible frames.

   Processing user input takes absolute priority over redisplay.  If you
call these functions when input is available, they do nothing
immediately, but a full redisplay does happen eventually--after all the
input has been processed.

   Normally, suspending and resuming Emacs also refreshes the screen.
Some terminal emulators record separate contents for display-oriented
programs such as Emacs and for ordinary sequential display.  If you are
using such a terminal, you might want to inhibit the redisplay on
resumption.

 - Variable: no-redraw-on-reenter
     This variable controls whether Emacs redraws the entire screen
     after it has been suspended and resumed.  Non-`nil' means there is
     no need to redraw, `nil' means redrawing is needed.  The default
     is `nil'.
