You’ll need to call this after speedbar-mode is loaded for it to have effect. Since you’re using use-package, you can accomplish this by adding it as a :config option, e.g., (use-package sr-speedbar :ensure t :defer t :config (define-key speedbar-mode-map "\M-p" nil) ...) More generally, you can use eval-after-load: (eval-after-load "speedbar" '(define-key speedbar-mode-map "\M-p" nil))https://jaaved.netlify.app/notes/202105201636-yasnippet/Sat, 14 Jan 2023 20:07:19 +0400https://jaaved.netlify.app/notes/202105201636-yasnippet/Commands and functions fc # position ease box interval due front 2.20 4 13.01 2021-11-01T16:30:58Z `yas-expand` bound > TAB tries to expand snippet abbrev before point. yas-insert-snippet > my custom shortcut is > C-. list all the available snippets, with names `company-yasnippet` > tries to auto complete available snippets > C-, helps in completing with snippet key yas-describe-table > lists table of snippets available in the current mode with key and description
