Re: EMACS or death
"*No* possible editing power or functionality is possibly worth making me learn a new UI in the 3rd decade of the 21st century."
Well said.
Hence vi. That was what was the available editor when I started using Unix.* IME one of the best things about it are ex mode commands for making bulk changes. The notation has passed into common use here with expressions such as s/emacs/vi/g
I've just taken a quick look at your preferred tilde and rebounded promptly: grey on medium blue. These old eyes prefer the contrast of black on white with white on black as an acceptable alternative. I do take your point about CUA. It's been built into many GUI interfaces, at least to some degree, for a long time except those which seem insistent into drifting off into realms unknown.
* Not strictly true, the first Unix box was supplied without a few things including vi & C shell but had the Rand editor which I've never seen since. First day in a new job where it was vi rather than Rand was a slight panic,managed by vague memories of ex commands and an after-work dash to Dillons. The hastily bought book on vi is still in my bookshelves.
