A fully-resolved editor action — what the keymap emits, what the buffer consumes.

Variants

Move(Motion)

Move every cursor by motion.

Operator(Operator)

Begin an operator (the d/c/y key). The editor enters operator-pending: the next motion composes into an Action::ApplyOperator. Resolved by the operator-pending FSM, never executed directly.

ApplyOperator

Apply a pending operator over a motion (delete-word, yank-line, etc.).

Fields

op: Operator

motion: Motion

Edit(Edit)

Apply a primitive edit at each cursor.

ChangeMode(Mode)

Enter the given mode.

Command

Run a named command (via the command registry).

Fields

name: String

args: Vec<String>

InsertChar(char)

Insert a character at each caret. Separate from Edit so the keymap can stay ignorant of rope details.

SubmitCommand

Submit a minibuffer / command-mode line (e.g. :w, :q).

Undo

Undo / redo one change.

Redo

Save

Save the current buffer.

Quit

Quit the editor.

SearchOpen(Direction)

Open the search prompt in direction (the / and ? keys).

The prompt reuses Mode::Command rather than adding a mode variant: vim’s / IS the command-line with a different prompt character, and this module’s own doc states new modes are layered through pending state, not new variants. SearchState’s typed Option<Prompt> is what disambiguates a <CR> that submits a search from one that submits an ex-command — a discriminator that cannot be forgotten, unlike a bool.

SearchRepeat

n (reverse = false) / N (reverse = true) — jump to the next match, relative to the direction the search was committed with, so N after a ? search moves forward.

Fields

reverse: bool

SearchWord

* (reverse = false) / # (reverse = true) — search the whole word under the cursor. Literal, not regex: the word may contain . or [ and the user means those characters.

Fields

reverse: bool

ClearSearchHighlight

:noh — stop highlighting matches while keeping the pattern, so n still works. Distinct from cancelling a search.

PromptBackspace

Backspace inside a command-line or search prompt.

Key::Backspace was previously bound in NO mode, so the minibuffer could be typed into but never corrected — a typo meant Esc and start again. One action serves both prompts; the runtime routes it by whether a search prompt is open.

Pending

No-op — used when a key sequence is pending but not yet complete.
