I can understand why to use C-a, C-e, because laptop keyboards tend to have "Home" and "End" keys in strange places, but those... And Emacs documentation for some reason insists on using C-e, C-f instead of arrow keys.

Not a eMacs person, but as a vim user arrow keys are annoying to reach. Using control or vim bindings it is far easier for me

It's Emacs not eMacs! ;)

Just enable vim mode (`set -o vi`) and call it a day.

shhh, don't tell them there's a superior text editor out there, it's fun watching emacs users consistently do things the hard way

Who has time to move all of the way over to the arrow keys, tap a few times and then find the little tab on the J again? I have arrows behind a second layer on my keyboard with vim mapping, and I don't think I could give that up. If you spend all day in front of a keyboard you might as well learn to be efficient with it.

> I have arrows behind a second layer on my keyboard with vim mapping

Same here: second layer reachable from the hands' home position on the keyboard. Left thumb for the modifier + ijkl in my case (I like ijkl for it mimics an actual arrows key cluster).

It works everywhere: xterm / command line, Emacs, any editor / IDE really, any dropdown menu...

It's the way.

I really wish we could get a GNU Readline replacement with much stronger editing capabilities: better multiline support, mouse support, syntax highlighting, etc.

Command-A isn’t available on Linux in slack? How do people even function without basic function keys?

Let me introduce you to the Home key: https://en.wikipedia.org/wiki/Home_key

I've always pried this key and other useless keys off my keyboards. TIL.

Ahh yes. Freezing your terminal via control flow with Ctrl-s. It’s almost as bad as finding yourself trapped in vi with no obvious way to exit. But if I recall correctly, you can resume flow with Ctrl-q.

Indeed. And you can desactivate it too: I'm just running:

    stty -ixon

in interactive shells and Ctrl-s ain't an issue anymore.

If I do want to "pause" the output, teletype style, as if the seventies called or something, I pipe my command into less instead.

I've been disabling Ctrl+s since literally more than a decade and don't know what I'm missing. Probably not much.

Ctrl-R! Ctrl-R! Ctrl-R!

How many people have been on a screen sharing call and watched the other person tediously up-arrow through 5-10 commands to try to rerun what they just did? The single greatest productivity boost you can gift a CLI newbie is searching their command history. Everyone jumps on the Emacs nav keys (C-f, C-b, etc) or other editing trivia. No one has trouble editing a command in place but it certainly takes some people way too long to run a command from one minute ago.

Also, purely selfishly, it's goddamned painful to watch the up-arrow dance and it wastes so much time. I want to scream.

For extra boost, add fzf and its shell integration.

Seems quite cool - I don't suppose you have a copy of the .dict file linked in that blog post? the link is 503 :\

There's a link in the comments to it. https://github.com/jrus/cocoa-text-system/blob/master/KeyBin... Though I just have: "^w" = "deleteWordBackward:"; /* C-W Delete word backward */

Missed that - thanks :)
