Subject: (yasnippet) how to disable TAB <tab> C-i?
Date: Mon, 18 Jul 2022 15:29:37 +0000

Hello,

as per: https://github.com/joaotavora/yasnippet, I am sending an e-mail 
to you to ask for help.

I really like yasnippets, because it makes my workflow more productive, 
but I have not been able to disable the autocompletion with the TAB key:

* What I have tried
(use-package yasnippet :defer t :commands (yas-minor-mode)
  :bind
  (:map
   yas-minor-mode-map
   ("TAB" . nil)
   ("<tab>" . nil)
   ;; Expand with C-c m
   ;; (how?? yas--direct-{keymaps,org-mode})
   ("C-c m". yas-expand)
   ;; Change C-S-i to navigate back
   ("ESC TAB" . yas-prev-field)
   :map
   esc-map
    ;; Disable this to enable C-S-i to navigate back
    ;; (previously defined in bindings.el)
    ("\t" . nil)))

(with-eval-after-load 'yasnippet
  (setq yas-snippet-dirs (list "~/snippets/"))
  (yas--load-snippet-dirs)
  ;; allow to insert a snippet within a snippet
  (setq yas-triggers-in-field t)
  ;; Testing (above)
  ;; ;; Change trigger key
  ;; (define-key yas-minor-mode-map (kbd "C-i") nil)
  ;; (define-key yas-minor-mode-map (kbd "C-c m") 'yas-expand)
  ;; (define-key yas-minor-mode-map [(tab)]        nil)
  ;; (define-key yas-minor-mode-map (kbd "TAB")    nil)
  ;; (define-key yas-minor-mode-map (kbd "<tab>")  nil)
  )

* Current behaviour
1. I launch a snippet with C-c m
2. Inside, I type the name of another snippet, for clarity, assume it is 
tuk
3. I type [TAB], C-i
4. tuk gets expandedtuk

* Expected behaviour
1. I launch a snippet with C-c m
2. Inside, I type the name of another snippet, for clarity, assume it is 
tuk
3. I type [TAB], C-i
4. I get out of ttukhe first snippet (tuk does not get expanded).

tuk is this:
# -*- mode: snippet -*-
# name: latex-inline
# key: tuk
# expand-env: ((yas-indent-line 'fixed))
# --
\\($1\\)$0

How do I configure yasnippet so that snippets get expended with C-c m 
*only*? Thanks!
