+# @gregorlohaus/codemirror-helix
+
+[Helix](https://helix-editor.com/)-style modal editing for [CodeMirror 6](https://codemirror.net/).
+
+Selection-first editing with multiple selections, Normal/Insert/Select modes,
+goto & match modes, textobjects, surround, registers, counts, and search.
+
+> A **core motions subset** — broad coverage of everyday Helix keys, not full
+> parity. No tree-sitter textobjects, LSP gotos, macros, or jumplist.
+
+## Install
+
+```sh
+bun add @gregorlohaus/codemirror-helix
+# peers: @codemirror/{state,view,commands,language,search}
+```
+
+## Usage
+
+```ts
+import { EditorView, basicSetup } from "codemirror";
+import { helix } from "@gregorlohaus/codemirror-helix";
+
+new EditorView({
+  doc: "hello world",
+  extensions: [basicSetup, helix()],
+  parent: document.body,
+});
+```
+
+`helix()` needs a selection drawer for multi-cursor rendering — `basicSetup`
+(or `drawSelection()`) covers it.
+
+### Options
+
+```ts
+helix({
+  startInInsert: false, // start in Normal mode (default)
+  statusBar: true,      // show the bottom mode line
+  // Let an open autocomplete popup eat the first Escape instead of leaving Insert:
+  escapeGuard: (state) => completionStatus(state) === "active",
+});
+```
+
+## Keys
+
+Starts in **Normal** mode. The status line shows the mode, pending count,
+register, and selection count.
+
+| Group | Keys |
+| --- | --- |
+| Modes | `i`/`a` insert before/after, `I`/`A` line start/end, `o`/`O` open line, `v` select (extend), `Esc` normal |
+| Motion | `h j k l`, `w W b B e E`, `f t F T {char}`, `Alt-.` repeat find, `Home`/`End`, counts (`3w`) |
+| Goto `g` | `gg`/`Ng` line, `ge` end, `gh`/`gl` line ends, `gs` first non-blank, `gt`/`gc`/`gb` view top/center/bottom |
+| Select | `x` line (repeat extends), `X` line bounds, `%` all, `;` collapse, `Alt-;` flip, `Alt-:` forward, `,` keep primary, `Alt-,` remove primary, `(`/`)` rotate, `_` trim |
+| Multi | `s` select regex, `S` split, `K`/`Alt-K` keep/remove, `C` copy selection below, `Alt-C` above |
+| Match `m` | `mm` matching bracket, `mi{o}`/`ma{o}` inside/around (`w W p ( [ { < " ' \` m`), `ms{c}` surround, `md{c}` delete, `mr{c}{c}` replace |
+| Edit | `d` delete, `c` change, `y` yank, `p`/`P` paste, `R` replace w/ register, `r{c}` replace char, `~`/`` ` ``/`Alt-`` ` `` case, `J` join, `>`/`<` indent, `u`/`U` undo/redo |
+| Registers | `"{c}` select register for the next yank/delete/paste |
+| Search | `/` `?` search, `n`/`N` next/prev, `*` search selection |
+| View | `zz`/`zt`/`zb` center/top/bottom, `Ctrl-d`/`Ctrl-u` half page, `Ctrl-f`/`Ctrl-b` page |
+| Clipboard | `space y` copy, `space p`/`space P` paste (system clipboard) |
+
+`s`/`S`/`K`/`Alt-K` open a prompt and preview live as you type the regex;
+`Enter` commits, `Esc` restores the original selection.
