injectHeldKeyCodes

function injectHeldKeyCodes(): Signal<Record<string, string>>;

Defined in: injectHeldKeyCodes.ts:28

Angular inject-based API that returns a signal of a map from held key names to their physical event.code values.

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

Returns#

Signal<Record<string, string>>

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

Example#

@Component({
  template: `
    @for (key of heldKeys(); track key) {
      <kbd>{{ key }} <small>{{ heldCodes()[key] }}</small></kbd>
    }
  `,
})
export class KeyDebugComponent {
  heldKeys = injectHeldKeys()
  heldCodes = injectHeldKeyCodes()
}
