It’s sort of a silly question.
To customise emacs beyond clicking around in ‘customise’ you need to write elisp. If you learn little elisp then you can only customise it using other people’s code, if you learn a lot of it then you can write an mua.
You decide where you want to be on that spectrum.
(imo) you’re using it wrong, I made everything defer by default then rely on autoloads and/or :bind/:commands with light use of :after . 99% of things are lazy loaded after an hour or so of work on a > 1000 line .emacs . It’s not ideal and I should probably turn most of :commands into patches upstream for auto loads but I am lazy.
I feel like if I understood embark it would do that.
Such a weird and lazy question. emacs is over forty years old, has whole applications written in it and people have slowly modified their own configs for decades to be thousands of lines of code.
Come on mate, go download whatever version was current then from some old ftp site or choose a less mad hobby.
C-M-a means “hold control and meta at the same time and then press a”.
C-h k (hold control, press h, let go of h and control, press k) followed by key presses will tell you what emacs saw and what function it will run.
Have you read the whole tutorial?
C-h k then scroll and see what emacs thinks is happening.
emacs is not going to be a good fit for that style of work, unfortunately
why don’t you just try it and see if you personally like it for your personal tasks and requirements
This is not a useful plan. Building eMacs produces a binary that depends at runtime on loads of libraries that you haven’t installed on the outer system.
Just don’t bother doing this.
