You gotta try out using describe-symbol because it is usually what you really want from describe-function and describe-variable.

The most useful part is that it instantly teaches you when there are both a variable and a function with the same name. Sometimes it is surprising and better to know right away. For example M-x describe-symbol RET emacs-version RET:

emacs-version is an interactive compiled Lisp function in ‘version.el’.

(emacs-version &optional HERE)

Display the version of Emacs that is running in this session.
With a prefix argument, insert the Emacs version string at point
instead of displaying it.
If called from Lisp, by default return the version string; but
if the optional argument HERE is non-nil, insert the string at
point instead.

Don’t use this function in programs to choose actions according
to the system configuration; look at ‘system-configuration’ instead.

  Probably introduced at or before Emacs version 19.20.

emacs-version is a variable defined in ‘C source code’.

Its value is "28.1"

Version numbers of this version of Emacs.
This has the form: MAJOR.MINOR[.MICRO], where MAJOR/MINOR/MICRO are integers.
MICRO is only present in unreleased development versions,
and is not especially meaningful.  Prior to Emacs 26.1, an extra final
component .BUILD is present.  This is now stored separately in
‘emacs-build-number’.

  Probably introduced at or before Emacs version 19.20.

Yes. You can do it with server-eval-at instead of emacsclient.

It took days too long for me to understand the solution.

In honor of that effort, in case someone out there can benefit, I wrote down all of my notes here.

Happy Hacking!

When you try to align your Emacs frame flush on macOS and it just doesn’t quite reach the edge

You can fix it with

(setq frame-resize-pixelwise t)

Via Reddit.

Here are some pretty good configuration options to copy.

Seriously they are pretty good and very objective. I tried to keep as little subjective preference in there. Although I definitely failed at least partly, there is good stuff in there.

And it is super short anyway.

When non-Emacs users observe Emacs users laboring over their key binding configuration their typical range of reactions include finding it to be interesting, surprising, remarkable, strange, weird, incredible, striking, bizarre, deviant, eccentric, freakish, monstrous, incomprehensible, inconceivable, incredible, unimaginable, and unthinkable. With that range reactions in mind it is self-evident that if you are reading this then you already know why you want to use more of the Emacs’s modifier keys you just want to know how. The purpose of this project is to capture one way of using all of Emacs’s modifier keys.
