I am trying to rebind some keys for info-mode without success. I am not sure whether I am missing something, or whether a special hook is required. I am using the following hook in my init.el:

(add-hook 'info-mode-hook
          (lambda ()
            (message "setting up info-mode")
            (local-set-key (kbd "C-c l")
            (local-set-key (kbd "g g")
            (local-set-key (kbd "C-c g")

But when I run C-h i to open info-mode, my custom bound keys above do not work and I do not get any message like "setting up info-modein myMessages` buffer.

I have evaluated the above hook with an empty emacs config (emacs -q), and I have many other mode hooks that are working fine.

Any suggestions to help troubleshoot or resolve this issue would be appreciated! I am happy to clarify anything as well.

    Try using a capital "I" for "Info-mode . . . " -- e.g., Info-mode; Info-mode-hook. It's unfortunate that the author decided to break from tradition with lowercase letters, but that's how it goes sometimes. To see more, type: M-x find-library RET info RET Some of the variables/functions are lowercase -- it's a hodge-podge mess if you ask me.

  • Yep, that works! If you add your comment as an answer, I will happily accept it :D

  • Take note that C-h v major-mode would tell you Info-mode, and that mode hooks are always the mode name with a -hook suffix.

The built-in Info-mode uses a combination of initial uppercase and/or all lowercase letters for the various variables/functions/faces. There may be a rhyme or reason, but it quite frankly escapes me as I read through the source-code. I wish there were a better method than familiarizing ourselves with the source code by typing M-x find-library RET info RET and reading through it with some targeted word searches, but I don't really have a better method -- except perhaps find-variable/find-function/find-face and trying both info- with a lowercase and Info- with an uppercase.

In the context of this particular question, the major-mode is Info-mode with a capital letter "I" and the hook is similar -- i.e., Info-mode-hook with a capital "I".

  • Thanks! Hopefully someone in the future will find this very helpful.
