Hi,I think I've found a little bug in info-look.el. If anyone out there regularly uses info-look.el, could they please check the following and get back to me? % emacs -q In the *scratch* buffer, type "C-h S defun RET". The frame should divide into two: the top window shows *scratch* and the bottom window shows the definition of "defun" from the elisp *info*. Still in the scratch buffer, type "C-h S setq RET". This time the *scratch* buffer disappears and is replaced by another window showing *info* for setq; so now, both windows are showing an info node, but the scratch buffer has gone. I think this behaviour is wrong, and that if the *info* buffer is already visible, it should not be viewed again in another window. I think have tracked down the problem to the call in info-lookup whereit calls Info-goto-node.I think this problem can be solved by using save-window-excursion, but then on the second call to C-h S, the highlighting is not shown. Anyone have a better idea of how to solve this?
I think it is caused by the default value of same-window-buffer-names, which includes "*info*". Here's a patch: *** emacs-21.3/lisp/info-look.el.orig Fri Oct 18 19:21:07 2002 --- emacs-21.3/lisp/info-look.el Mon Feb 2 18:19:02 2004 *************** *** 338,345 **** (if (and info-frame (display-multi-frame-p) (memq info-frame (frames-on-display-list))) ! (select-frame info-frame) ! (switch-to-buffer-other-window "*info*"))))) (while (and (not found) modes) (setq doc-spec (info-lookup->doc-spec topic (car modes))) (while (and (not found) doc-spec) --- 338,347 ---- (if (and info-frame (display-multi-frame-p) (memq info-frame (frames-on-display-list))) !

(switch-to-buffer-other-window "*info*")))))) (while (and (not found) modes) (setq doc-spec (info-lookup->doc-spec topic (car modes))) (while (and (not found) doc-spec) -- Kevin Rodgers
