 * Changes in Emacs 22.1
 
+** Improved key bindings support when running in an xterm.
+When emacs is running in an xterm more key bindings are available. The
+following should work: 
+{C,S,C-S,A}-{right,left,up,down,prior,next,delete,insert,F1-12}.
+These key bindings work on xterm from X.org 6.8, they might not work on
+some older versions of xterm, or on some proprietary versions.

 ** Improved Thai support.  A new minor mode `thai-word-mode' (which is
 automatically activated if you select Thai as a language
 environment) changes key bindings of most word-oriented commands to
