Ki Editor - an editor that operates on the AST
https://ki-editor.org/ Ctrl + W
Ctrl + Shift + W
It really changed my perspective on interacting with the 'text' of a file.
VS Code, Zed, etc. have similar operations, but in my experience they expand and shrink too coarsely.
I love AST aware editing. I think it's one reason it's always been so nice to edit lisps. Stuff that is complicated to describe in javascript (and doesn't have LSP support) p much requires a whole AST parser, but in lisp it's just a simple list operation. When I go back typescript after a weekend of clojure, I reeaally miss slurp! and other paredit commands
The extent of my usage is having nice textobjects to easily interact with arglists and functions which aren't native to (neo)vim. Very cute and nice to just write "daf" somewhere in a function and just have it "just delete". Or hook it up with basic macros: search for regex, "daf".
I guess it's hard for me to edit things that I don't see right in front of me or aren't super simple changes (like name changes). Or at least, basic things I can reason about (such as finding by regex then deleting by textobject or something).
As for LSP's, I do use go to definition and rename all references, which is nice. But the huge structural refactoring part I have never really done. I don't really use many LSP features besides those two either...
Basically, I gotta up my editor game.
1. Orthodox. Mostly focused on looks and integrations.
2. Modal, Vim improvement. Focus on keeping basic Vim keybindings with minor improvements.
3. Modal, rethinking Vim approach.
Ki falls into the third category which I constantly monitor.
Which is Emacs.
(This is spoken with something close to affection; I look fondly on my former Emacs days. I'm probably more likely than not to enjoy the company of a human who has at least tried Emacs and had some thoughtful reaction to it. I may not use it now, but the ideas live on in how I think and what I expect. Editors that push the limits, whatever those limits are, are part of the old school ethos I love about programming.)
So Ed Visual Mode Improved Improved!

This is awesome! And I bet it arguably requires less logic to do so as well. Cool stuff.
Now I'm wondering how much effort it would be to get a ki integration (or at least an AST-first rewrite) in Zed

> As you can see, there's no single logical categorization for these keymaps, they are either lowercase-uppercase, normal-alt, left-right bracket, or outright unexplainable.
Word, End, Back, Change Word and even Change Inner (, etc are very logical to me and I feel like I'm talking to the editor when editing. I get that it doesn't make sense when one has learned another way to do it, but it does make total sense you just have to make an effort to try and understand it.
It's like learning and always driving automatic then calling manual "outright unexplainable". You simply learned another way and are conditioned into believing that's the one true way. It shows the creator comes from VSCode (multi-cursor is a useless feature, just use s/search/replace and get used to macros and a whole new world will open).
Just over a year ago I decided to switch to Neovim. The reason for switching was personal; I was struggling with what I'll call "clutter" in other tools and I wanted a tool that would reinforce, at least lightly, a mode of working that promoted focus on what I was working on, while making it easy to reference other files without loading up my editor with tabs and other visual clutter (buttons/menus) I don't care about most of the time.
I took the advice I seemed to bump into repeatedly: try out vim mode in my current editor before making the plunge.
I really struggled at first. It felt wildly foreign. All the shortcuts were nowhere near to the world I was familiar with.
As I was about to give up, I ran into some advice that was along the lines of "stop trying to memorize shortcuts and start thinking in terms of what you want to achieve" (words and motions in vim-speak).
Your example of [C]hange [I]nner is a great one; that one in particular was life changing. Sure there are some words and motions that do require memorization, but so many others just flow naturally. And once you start thinking in actions, it's easy to see how they can layer on top of each other in really elegant ways.
I'm not even here trying to tout vim-like editors, I'd wager there are many editors that have some semblance of this kind of interaction, but rather to reiterate there's a shift from a PoV of function vs. goal.
Again, I don't think this is "the right way" but rather one of many perspectives that works in context with the phenomenology of me.
Hey, one of the creators here, I actually daily drove Neovim for two years, before switching to Helix for a while, then finally Ki.
> multi-cursor is a useless feature
I was a Neovim macro user until I figured out how insane that was compared to multi-cursor after using Helix.
I also feel like macros are a more clunky and error prone way to do what substitutions can do. Almost never use them.
I think the same goes for multi-cursor, though.
Multi-cursor was the first plugin I installed when I moved from VSCode to Vim because I was used to hitting Ctrl+d to select all words and then replacing. Does Helix do something different?
1) First I reach for <C-v> for visual block selection if everything is neatly aligned.
2) Next choice is %s/search/replace(/c if I need confirm).
3) Macros, and I love it everytime I get to use them. I just record the movements, copy what I need to copy, paste it where I need to paste it, and it's repeatable for every line or block where the *formatting* matches. And this is the important part, the words don't matter. I still feel like a wizard using them.
As far as I understand multi-cursor option 3 is a no-go without macros if the words don't match. But macros don't care as long as the movements translate to the same edits. How does Helix multi-cursor work that make macros insane?
It's hard to explain unless you actually try Ki, because it is a paradigm shift
I'll give you that using the AST to select the references is an interesting addition to multi-cursor, but I still don't see how they would be useful compared to my current workflow.
Is there a good tutorial for some of these advanced text editing features?
In particular I’d like to get platform independent shortcuts / key bindings. I use both windows and MacOS daily, and it throws off my muscle memory for shortcuts like “go to beginning of line”
This, alongside the use of a variable means you can, in fact, build your own selection modes! Likewise, nvim does have a seperate select and visual mode.
This is primarily designed as an option to replicate the more traditional shift+movement selection and type to replace functionality of something like vscode or notepad, however it can be exploited as an additional layer for storing keybinds in a pinch

Unfortunately however, there's some shortcomings of neovim which make its control scheme impossible (at least not without some workarounds)
One of the biggest is ki's momentary layers feature.
Ki uses the kitty keyboard protocol to detect when a key is being held and when it is released in order to allow for unique actions when multiple keys are pressed simultaneously, and this functionality is a big part of what makes it so ergonomic.
For example, tapping c will copy the currently highlighted text, but pressing c and k simultaneously will duplicate the currently selected text to a new line below the current line.
While I'm currently chipping away at a pull request to introduce similar functionality to neovim itself, in the meantime, I'm needing to work around the issue by making a lot of concessions.
