Migration from define-key to bind-key with prefix-command

[Karl Voit]

Hi!

How can I define "define-key" commands with a global prefix-command to
bind-key(s) syntax?

I don't want to loose the ability to change my global prefix "my-map"
to a different one on one single place. I also want to keep my habit
of defining key bindings on many different places scattered all over
my init file and not on one single spot.

What I do have in my Emacs initialization file(s):

#+BEGIN_SRC elisp
(define-prefix-command 'my-map)
(global-set-key (kbd "C-c C-,") 'my-map)
(global-set-key (kbd "C-c ,") 'my-map)

[...]

;; scale text size (C-c C-, +/-)
(define-key my-map "-" 'text-scale-decrease)
(define-key my-map "+" 'text-scale-increase)

[...]

;; remove trailing whitespaces (C-c C-, " ")
(define-key my-map " " 'delete-trailing-whitespace)
#+END_SRC

What I think of (in totally wrong Elisp):

#+BEGIN_SRC elisp
(define-prefix-command 'my-map)
(global-set-key (kbd "C-c C-,") 'my-map)
(global-set-key (kbd "C-c ,") 'my-map)

[...]

;; scale text size (C-c C-, +/-)
(my-bind-key my-map "-" 'text-scale-decrease)
(my-bind-key my-map "+" 'text-scale-increase)

[...]

;; remove trailing whitespaces (C-c C-, " ")
(my-bind-key my-map " " 'delete-trailing-whitespace)
#+END_SRC

Or do I have to change my habits, get rid of my unified prefix
(my-map), and use define-key with repeating "C-c C-," prefix?

Thanks!
