Thank you. I made a function, and now it works nicely this way: (defun hyperscope-view-local-map (id column) (interactive) (let ((map (make-sparse-keymap))) ;;(set-keymap-parent map (make-composed-keymap view-mode-map)) (define-key map "q" 'quit-window) (define-key map "i" (lambda () (interactive) (hyperscope-view-with-mode id (cond ((string= column "hlinks_description") "hlinks_text") ((string= column "hlinks_text") "hlinks_description") (t (error "Cannot find column")))))) (define-key map "e" (lambda () (interactive) (hyperscope-edit-with-mode id column) (kill-this-buffer) (hyperscope-view-with-mode id column))) (use-local-map map))) When I wish now to use the map, I just provide one line: (hyperscope-view-local-map id column) -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
