I am trying to rewrite the following line from my GNUEmacs .emacs file: (global-set-key [?\C-\S-r] 'revert-buffer) I believe the following should work: (define-key global-map '(control R) 'revert-buffer) When I do: M-x describe-bindings I get: C-R revert-buffer BUT WHEN I do: M-x describe-key And type "control-shift-r" -- I get: C-r runs `isearch-backward' I am running XEmacs 21.0 "Saanen-pre4" [Lucid] (i386-pc-cygwin32) of Fri May 15 1998 on MONKEY via xemacs -q -no-site-file. How does this behave on non windows platforms? -Dan
