make ctrl-+ increase font size?

[Simon Josefsson]

Ctrl-+ seems unused right now.  Can we make it a short-cut for
increasing the font size?

Ctrl-+ is used to increase the font size in many GNOME applications (and
other applications too) so it would be nice to be consistent here.

Ctrl-- is already taken, but maybe it isn't that important?

I, for one, would be against it. Let's keep that key for users.

It's easy enough for any user to bind `C-+' to whatever command s?he wants,
including one that increases the font size. (Of course, you need a command that
does that. ;-))

[I bind `C-+', for example, to a command that toggles showing crosshair
highlighting at point. And I bind a command that increases the font size to
`C-wheel-up' (and to `S-mouse-1', except in some modes).]

And yes, `C--' is very important. Many commands provide alternative behavior
when you use a negative prefix arg, and `C--' is useful for that. Just `C--'
alone (no following digits) is the quickest way to reverse the behavior of many
commands that simply test the sign of the prefix arg.

There was already a discussion about this, leading to the current
compromise bindings of C-x C-+ (etc).  You can search the emacs-devel
list for that if you want.

I've bound C-+ and C-- to text-scale-increase and text-scale-decrease
respectively, but also bound M-+ and M-- to increase/decrease the font
size in every buffer. I agree that C-x C-+ and C-x C-- can be a bit
cumbersome to type, but seeing as rebinding C-- (and M--) would break
negative-argument, it's certainly a bad idea to make those keybindings
default.

But how about making C-x M-+ and C-x M-- default bindings for
increasing/decreasing the font size in every buffer? Has that been up
before? Would that break anything?

Ah, sorry I had missed that.  I have put

(define-key global-map [?\C-+] 'text-scale-increase)
(define-key global-map [?\C--] 'text-scale-decrease)

in my ~/.emacs and can live with it, although I suspect the concern will
come up again in the future.

Then there's the fact that Emacs is not a Gnome application...
