+
+@cindex Variable-size fonts
+@cindex Toolbar support
+Emacs 21 features a thorough rewrite of the display engine. The new
+display engine supports variable-size fonts, images, and can play sounds
+on platforms which support that. As a result, the visual appearence of
+Emacs, when it runs on a windowed display, is much more reminiscent of
+modern GUI programs, and includes 3D widgets (used for the mode line and
+the scroll bars), a configurable and extensible toolbar, tooltips
+(a.k.a.@: balloon help), and other niceties.
+
+@cindex Colors on character terminals
+@cindex TTY colors
+In addition, Emacs 21 supports faces on character terminals. This means
+that you can now have colors when you run Emacs on a GNU/Linux console
+and on @code{xterm} with @kbd{emacs -nw}.
