createHeldKeyCodes

function createHeldKeyCodes(): () => Record<string, string>;

Defined in: createHeldKeyCodes.ts:35

SolidJS primitive that returns a signal of a map from currently held key names to their physical event.code values.

This is useful for debugging which physical key was pressed (e.g. distinguishing left vs right Shift via "ShiftLeft" / "ShiftRight").

This primitive uses useSelector from @tanstack/solid-store to subscribe to the global KeyStateTracker.

Returns#

Signal accessor for record mapping normalized key names to their event.code values

() => Record<string, string>

Example#

function KeyDebugDisplay() {
  const heldKeys = createHeldKeys()
  const heldCodes = createHeldKeyCodes()

  return (
    <div>
      <For each={heldKeys()}>
        {(key) => (
          <kbd>
            {key} <small>{heldCodes()[key]}</small>
          </kbd>
        )}
      </For>
    </div>
  )
}
