(interactive) (let ((mode (list (intern (read-string "Mode: "))))) (unless (functionp mode) (with-current-buffer (switch-to-buffer-other-window "my-describe-mode") (insert (documentation mode)))))) This inserts "Keyboard macro." into the buffer (without the quotes). I'm not too sure about what I'm doing here ... When I use (help-buffer) instead of "my-describe-mode" for a buffer, the (help-buffer) might be read-only? -- GNU Emacs 24.4.50.2 (x86_64-unknown-linux-gnu, X toolkit, Xaw3d scroll bars) of 2014-08-17 on yun.yagibdah.de
