Import

import { Composite } from "@typed/ui/index";

Access Composite.typeaheadKey through the imported Composite export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare function typeaheadKey(event: KeyboardEventLike): string | null;

Why

Separating this deterministic policy from event wiring lets applications test it directly and reuse it in custom composites.

Ownership and lifetime

This is a synchronous calculation. It acquires no resources and does not mutate the input array, state, event, or DOM.

Examples

import * as Composite from "@typed/ui/Composite";

const key = Composite.typeaheadKey({ key: "A" });

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
