[PATCH] special handling for `iso-next-group' is needed

Hello, I've finally properly configured my xkb and noticed the following misfeature (other users are reporting that, too). Pre-notice for non-English-only users: when xkb switches "Xkb Group" (e.g., from English to Cyrillic), it sends a special keysym `iso-next-group' to a program. Xemacs needs to somehow handle this keysym specially in two cases: - when user is switching the Xkb group, XEmacs says that "'iso-next-group' not defined". It should not. The following patch fixes that for both Mule and non-Mule (thanks to awn for proper defun) (is the [Control iso-next-group] handling really necessary?): =================================================================== RCS file: keydefs.el,v retrieving revision 1.1 diff -u -r1.1 keydefs.el --- lisp/keydefs.el 2001/07/28 19:11:19 1.1 +++ lisp/keydefs.el 2001/07/28 19:13:35 ＠＠ -654,4 +654,16 ＠＠ (define-key global-map 'insertchar 'function-key-error) (define-key global-map 'deletechar 'delete-char) +;;; Special handling for `iso-next-group' + +(defun noop-keysym () + "Noop function that doesn't abort the isearch mode." + (interactive) + (if isearch-mode (isearch-message)) +) + +(put 'noop-keysym 'isearch-command t) + +(global-set-key 'iso-next-group 'noop-keysym) + ;;; keydefs.el ends here Second issue is with "C-h k" sequence. You cannot look what is bound to a Cyrillic character. When you try to do that, the sequence of keys pressed is C-h k iso-next-group Cyrillic_ef and so it shows you what is bound to 'iso-next-group' keysym. I can not understand how to fix that. C-h k should somehow ignore certain keysyms completely, or something like that. The second issue is less important than the first one, which I consider worth fixing in the next XEmacs release.
