26.1-rc1: global-set-key suggestions

Hello.

I'd like to suggest the following improvement to the out-of-the-box
behaviour on apple-darwin, NS appkit :-

    ;;
    ;; Allow Command-Plus-or-Minus to text-scale fontsize.
    ;;

    (global-set-key (kbd "s-+") #'text-scale-increase)
    (global-set-key (kbd "s-=") #'text-scale-increase)
    (global-set-key (kbd "s--") #'text-scale-decrease)

Why not the C-+ etc. bindings used on the other platforms?

The bindings for font size change are :-

C-x C-+
C-x C--

Going native and being consistent with other apps on the platform is a pleasant experience; and, for beginners, it makes plain and simple sense, at least until, they've done the tutorial and have tried `M-x customize'.

Being unable to naïvely change the fontsize means the beginner has to endure the struggle of reading the wrong sized font for them initially. Or, every beginner has to hit a search engine to discover how to make the change for themselves.

Lastly, the Command-Plus-or-Minus is a simple two finger combination press which is easier to type than the C-x separately followed by C-plus-or-minus. Other native platform keybindings are already there out of the box, such as, Command-W.

I interactively change the text size often enough to use these custom
keybindings:

  (global-set-key (kbd "C-+") 'text-scale-increase)
  (global-set-key (kbd "C--") 'text-scale-decrease)
  (global-set-key (kbd "C-=") 'text-scale-adjust)

which is what I also use in other applications (e.g. Firefox) on a
GNU/Linux machine.  I thought C-+/- was pretty standard.

C-+ and C-= are free in Emacs, but C-- is not, emulating C-u -, but
I don't really mind having to type C-u - instead of C-- when I need.

2 cents,

MacOS commonly replaces C-X commands on other platforms with s-X.
Amusingly it means you get both emacs style bindings (e.g. C-a to move
to start of line) alongside CUA type bindings (e.g. s-a to select
all).

Looks like the macOS super bindings will interfere with s--, which is
bound to center-line. center-line is also bound to M-o M-s, so I don’t
think that losing the s-- binding would be a huge problem.

This sounds like a good change, too late for Emacs 26, though.

Thanks. I like that. I'll use that on my personal "s-=" mapping.

Is there an equally quick way to set permanently the zoomed fontsize? to store in Default's height :-

- M-x customize
 + Faces
   + Basic Faces
      + Default
         + Height

Beyond Emacs 26, having Default's Foreground/Background set colors according to time of day or level of ambient lighting is nice to have. For example, a totally black background reverse video effect is preferable when almost all the lights are off. A behavior that appropriately sets an inversely related foreground color given a slide in background color ranging from gray100 to gray0 would do.

Thanks are also owing to siraben who is behind the push to modernise bignum in calc.el.

The three liner at the start of this thread came from siraben. Thanks siraben.

Absolutely 100% agreed. Binding s-+, s-=, s-- would be an unambiguous
improvement in user experience on macOS with no downsides that I can
see. In fact, I may do this now in my personal configuration.

Binding C-+ etc. instead would be a mistake, at least on macOS.

I'd prefer binding these to a function that changes the font size on the whole frame, rather than just the current buffer.

See `zoom-frm-in' and `zoom-frm-out', in `zoom-frm.el'.

Or `zoom-in' and `zoom-out' (same library), which you
can use for both frame zooming and buffer zooming.

This is exactly what I do in my init file:
https://github.com/siraben/dotfiles/blob/master/emacs/.emacs.d/modules/siraben-fonts.el

Specifically, this is done by using `set-frame-font' which means 
elements such as the mode line are enlarged as well. Note that I am 
binding the font size changes to C-+, C-- and C-=, but it could easily 
be done with s-+, s-- and s-= respectively.

I don't see any conflicting key bindings with macOS. What are other 
maintainers' thoughts on this?

I’m no longer sure if we’re talking about just binding these keys on
the NS port or generally, but if it’s just the NS port then I have no
problem with either option. Resizing everything seems to match up most
closely with the other apps I use, but I’m not a heavy user of macOS
specific apps, so I can’t say whether it would be expected behaviour
or not.

Just to add another perspective....

I use Emacs on macOS at work and on GNU Linux at home. So for me, one of
the great things about Emacs was/is consistency in key bindings across
platforms. If we start making bindings different depending on the platform,
then you lose that level of consistency.

As this is Emacs, this is not a huge issue as it is easy enough to set them
to whatever I want, but thought I'd just mention that making bindings
platform dependent may have a downside for those who work in Emacs from
different platforms.

Tim

P.S. I've been using Emacs for so long, I tend to change the OS bindings to
match with Emacs rather than the other way round. Unfortunately, unlike GNU
Linux, macOS does not offer the same level of flexibility in this area

Indeed, there's a tension in this respect.  Ideally, we should provide
sets of customizations which better integrates Emacs into various OSes,
which users can then choose to enable or not.

A kind of "custom-theme" for that would be great, but currently
custom-themes don't work well for that since they can't really provide
key-bindings.

There could be money to be made selling the perfect Emacs physical keyboard with key-binding-themes included, like those stealthy gamer’s keyboards but for programmers and readers.

I switch between the smaller Apple keyboard and fullsize Thinkpad keyboard, both are without the numpad, and I really dislike:

1. typing C-x ; smallest left finger on `caps lock’ ; middle finger on x

2. the four extremely tiny arrow keys and the inverted T configuration

I find the ergodox good for this.

https://gitlab.com/jave/jv-ergodox

The repo contains a fork of Ergodox firmware, and some elisp to generate
new firmware with new emacs oriented keyboard layouts.

I’d like a dedicated Emacs variant of Vortex Race 3 in color with:

- bottom left fn-key does C-x
- four normal sized oneline of keys right of Spacebar for arrows
- dedicated forward/backward keys for
  + pages
  + paragraphs
  + sentences
  + words
  + characters
- dedicated top/bottom key for programming like begin/end of function goto

  ergodox.org doesn’t but ergodox.io does get to a page

How about a dedicated Emacs mini keypad the size of 13⨯21cm - 5⨯8¼ paper? designed by Moleskine® in Italy, set at the retail price of a mouse and placed diagonally from the top corner of a conventional keyboard.

The NS port already has over 40 ‘NS‐like’ bindings and has done since
it was merged in ten years ago.

Super thanks.

The Mac Port doesn't do the super-key at all, for example, for to:

;;(Define-key global-map [s-right] 'ns-next-frame)
;;(define-key global-map [s-left] 'ns-prev-frame)

Interestingly, Mac Port has assigned `fn-left` to perform C-a, <home>.

A search for `keyboards emacs` on Amazon shows four year old stickers, no keyboards, yet.
