Import
import { moveByKey } from "@typed/ui/Composite";Signatures
export declare function moveByKey<Value, CompositeState extends State, E, R, E2, R2, Element extends object>(event: KeyboardEventLike, options: MoveOptions<Value, CompositeState, E, R, E2, R2, Element>): Effect.Effect<boolean, E | E2, R | R2>;Why
The operation exposes Composite’s transition directly so callers can compose it in Effect programs and native event handlers.
Ownership and lifetime
The returned Effect performs the update or DOM side effect only when run, preserves the declared error and service channels, and retains no resources after completion.
Example
Import with import { moveByKey } from "@typed/ui/Composite"; Extend the Composite.makeState
runnable setup. Inside the linked Effect
program run yield* moveByKey({ key: "ArrowDown" }, { state, collection }), then read state to
observe the active id selected by the current orientation and RTL policy.
