(let ((a 1)) (setq a 10)) ⇒ 10 Immediately thereafter: a - Symbol’s value as variable is void: a because `a' variable was defined within `let' enclosure, it will not survive after the `let' enclosure get executed. Instead: (defvar my-mode-map (let ((map (make-sparse-keymap))) (set-keymap-parent map texinfo-mode-map) (define-key map (kbd "d") #'my-function) (keep-defining) (keep-defining) map) ;; return `map' here "Describe your map") ;; Define your derived mode (define-derived-mode my-mode texinfo-mode-map "My mode name" "Documentatio") (defun my-function () (interactive) (my-mode) (use-local-map my-mode-map)) add hook to my-function or run it interactively -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
