Assign TAB in markdown mode

Question

Running emacs 25.2.2, general, evil and markdown-mode installed from MELPA.

The problem is when I hit TAB on a heading in a markdown file, it does not cycle visibility of content.

C-h k TAB shows it is assigned to evil-jump-forward.

So, in my init.el, I added:

(general-def 'markdown-mode-map
  "TAB" 'markdown-cycle)

But still TAB is assigned to evil-jump-forward.

How do I assign TAB to markdown-cycle in markdown-mode?

Moreover, can I assign it such that only when the cursor is on a heading, it is assigned to markdown-cycle but at other locations, it is assigned to evil-jump-forward?

Answer 1

I've been looking into this as well. The reason your attempt isn't working, is because of evil and the way it binds keys to a higher level keymap (as far as I understand the matter).

Anyways, you can bind directly to the corresponding evil state you want to use the key in.

The following should do the trick:

(evil-define-key 'normal markdown-mode-map
       (kbd "<tab>") 'markdown-cycle)

(You might need to hit tab twice if there are no subheadings.)

The package evil-markdown provides much more complete integration with evil. Not on MELPA, unfortunately, so you'll have to install it manually. Check it out on https://github.com/Somelauw/evil-markdown.

Answer 2

Supporting the previous answer, I think <tab> needs to be replaced with TAB. For me, snippet in above answer didn't work but the following snippet worked:

(evil-define-key 'normal markdown-mode-map
  (kbd "TAB") 'markdown-cycle)

All the change is that I have used TAB instead of <tab>.
