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)
