I've not used Emacs to edit a file since 1994 and I hadn't used it for very long back them.
But I seem to remember after these 30 years that was something simple, like Ctrl-X Ctrl-S to save, and Ctrl-X Ctrl-C to quit.
Edit: I don't have Emacs installed absolutely anywhere; but I went to a machine provided by the GCC Farm project and tried it there. I remembered right.
Good for you. In 1994 I was mainly supporting DOS, Windows for Workgroups, Novell Netware, and DEC VAX/VMS. There was no xNix of any form in the UK branch of the company, and I think the HQ mainly ran on much the same stuff with some added Classic MacOS.
The point being that I learned literally dozens of editors and UIs in the 1980s and early 1990s... and then CUA came along and swept it all away, and I never looked back.
I wrote much of the original Wikipedia article on CUA:
I never ran Emacs, never had any reason to learn Emacs, so I never did.
I did learn WordStar, WordStar 2000 (totally different), WordStar Express (totally different again), WordPerfect, MultiMate, DisplayWrite, MS Word 4.x and the different 5.x and the different 6.x, plus WinWord 1 and the different 2, and LocoScript, and The Last Word, and Edlin, and DOS EDIT, and many many more.
I am very much not unable to learn new editors. But for over 30 years now, I haven't had to. And that's wonderful and I am absolutely not learning another new different editor now, at over half a century old.
Any editor that wants me to try it must conform 100% to the CUA standard, or it can die in a fire. Weird editor keystrokes are 1970s/1980s stuff, and keeping them 40 years is inexcusable.
