Imenu on Steroids

If you haven’t used imenu, do this, load up some source code or an org-mode file, and:

Slick. The problem is you have to either use the mouse, or do a lot of typing with tab to get to the function or header you want.

Assuming you have use-package installed to both install and configure packages, put this in your .emacs file and smoke it:

(use-package idomenu
    :ensure t
    :bind ("C-c i" . idomenu))

Now, you have a key binding to search your functions using IDO’s sweet approach to text selection.

If you are mousy or don’t want the visual clutter associated with increasing your mini-buffer, I suggest using imenu+ and its expansion on the standard menu support for imenu:

(use-package imenu+
    :ensure t
    :init (add-hook 'prog-mode-hook 'imenup-add-defs-to-menubar)
          (add-hook 'org-mode-hook  'imenup-add-defs-to-menubar))

Finally, if you are a Helm person, this approach creates a list of all functions/headers in a side buffer making it easier to see more options. Good for when you are looking at new source code:

(use-package helm
    :ensure t
    :bind (("C-c M-i" . helm-imenu)))

Next time, we should talk about tags…
