Reset C-, only for the org-mode case

Reset C-, only for the org-mode case

[michael-franzese]

Have been using the following keybindings to change the text height.

(global-set-key (kbd "C-,") 'text-scale-decrease)
(global-set-key (kbd "C-.") 'text-scale-increase)

But in org-mode C-, is already being used for org-cycle-agenda-files

C-'
C-, (org-cycle-agenda-files)

It was suggested to me that I can reset C-, and then apply my new keybinding
to execute "text-scale-decrease".

I would like to reset C-, only for the org-mode case.  What can be done?

global-set-key changes the global binding, not the binding local to
Org mode.  I suggest to read the node "Rebinding" of the Emacs manual,
including "Init Rebinding" to which it cross-references, to understand
the difference between these two, and also learn how to solve your
particular problem.

I have applied the following and gets things to work as I liked.

Is it good enough?

  (define-key org-mode-map (kbd "C-,") 'undefined)
  (define-key org-mode-map (kbd "C-,") 'text-scale-decrease)

The first line doesn't do anything as you bind the same key to
something else the second line.

You can add a hash before function names, like this:
#'text-scale-decrease

"C-," in already bound in org-mode

Was not aware one can use #' with emacs code, but only with user defined code.

Doesn't matter, you don't have to bind it to `undefined'
first :)

Oh no, it is the same code, the part of Emacs that is Lisp,
that's the same Lisp.

So it is a bit different than with the usual "unset-key"
or "set-key" to nil.

(global-set-key (kbd "C-e") nil)
(global-unset-key (kbd "C-e"))

? :)

What is it that you want to do? You want this?

  (define-key org-mode-map (kbd "C-,") #'text-scale-decrease)

Then it is enough :)

Now it is `text-scale-decrease' and it doesn't matter what it
was before or if it was set n times to n different values...

Year zero. No tradition. No history!

I wrote an example with global-set-key where you have to unset it first.

This means that define-key works a bit different than global-set-key.

Yes, because in org-mode the C-, was already used to do some other thing.

> Year zero. No tradition. No history!

Depends which year zero you are talking about.  Many things happened before the
christ story, if that happened at all!

You set it to x and it is x. The past doesn't matter when that
happens and after there is no record.
