Is there any handy way to view a custom key map?

[Jean Louis]

I have plethora of various screens displaying lists of items from the
database. Different database tables have different key maps.

Example:

(defvar rcd-db-mode-map 
  (let ((map (make-sparse-keymap)))
    (set-keymap-parent map tabulated-list-mode-map)
    (define-key map (kbd "/") #'rcd-tabulated-filter)
    (define-key map (kbd "G") #'goto-line)
    (define-key map (kbd "Q") 'rcd-db-kill-database-buffers)
    (define-key map (kbd "U") 'rcd-tabulated-remove-marks)
    (define-key map (kbd "V") #'rcd-tabulated-id-to-register)
    (define-key map (kbd "\\") #'rcd-tabulated-filter-reset)
    (define-key map (kbd "d") #'rcd-db-delete-tab-database-entry)
    (define-key map (kbd "e") #'rcd-db-edit-tab-database-entry)
    (define-key map (kbd "g") #'rcd-tabulated-refresh)
    (define-key map (kbd "j") #'next-line)
    (define-key map (kbd "k") #'previous-line)
    (define-key map (kbd "m") #'rcd-tabulated-mark-id)
    (define-key map (kbd "u") #'rcd-tabulated-unmark-id)
    (define-key map (kbd "z") #'rcd-tabulated-refresh)
    map)
  "The basic RCD database keymap")

Similarly to command C-h m I would like to display those key bindings,
though separate from C-h m screen. 

Something like this below would be fine:

Key             Binding

Q               rcd-db-kill-database-buffers
U               rcd-tabulated-remove-marks
V               rcd-tabulated-id-to-register
d               rcd-db-delete-tab-database-entry

I would even prefer that key bindings have their description, so that
instead of the name of function under "Binding" there appears human
readable text something like "Remove Marks" instead of
"rcd-tabulated-remove-marks".

Does such function or opportunity exists anywhere?
