Below is the entirety of my Evil key bindings in init.el:

(evil-define-key 'normal 'global (kbd "SPC") (make-sparse-keymap))
(evil-define-key 'normal 'global (kbd "SPC TAB") #'ivy-switch-buffer)
(evil-define-key 'normal 'Info-mode-map (kbd "SPC") (make-sparse-keymap))
(evil-define-key 'normal 'Info-mode-map (kbd "SPC SPC") #'Info-scroll-up)

The end result of this is as follows:

  • In Emacs-Lisp mode, SPC TAB is bound to ivy-switch-buffer; this is expected.
  • In Emacs-Lisp mode, SPC SPC is bound to Info-scroll-up; this is unexpected.
  • In Info mode, SPC TAB is undefined; this is unexpected.
  • In Info mode, SPC SPC is bound to Info-scroll-up; this is expected.

It seems to me (in one sentence) that the global config is not global and the local config is global. This is the opposite of what I would expect.

The Info-scroll-up binding is defined on Info-mode-map and has effect even when Info mode is not active. Why?

The ivy-switch-buffer binding is defined globally, but does not work when I am in Info mode. Not only does it not work, but it is undefined. It's not that SPC TAB has been replaced by another command, SPC TAB is undefined (and SPC is a prefix key). Why?

I can't form any mental model of why Evil / Emacs is behaving this way. Why is it behaving this way?

  • Please look at the Emacs manual on keybindings, and then the evil manual on how to do keybindings in evil globally and in specific modes. – Dan Nov 15 '19 at 21:54

    @Dan I have read all 11 pages of the Evil manual twice. – Buttons840 Nov 15 '19 at 22:08

This works as expected:

(evil-define-key 'normal 'global (kbd "SPC") (make-sparse-keymap))
(evil-define-key 'normal 'global (kbd "SPC TAB") #'ivy-switch-buffer)
(evil-define-key 'normal Info-mode-map (kbd "SPC") (make-sparse-keymap))
(evil-define-key 'normal Info-mode-map (kbd "SPC SPC") #'Info-scroll-up)

Notice that Info-mode-map is not quoted like it was in the original question.

The evil-define-key docs mention you can pass 'global' or 'local as the second argument. I'm not sure what it does if you give it some other quoted value like I was doing, but now that I'm calling evil-define-key correctly it works the way I would expect.
