How to use the is-hotkey.isHotkey function in is-hotkey

// Parse the initial location
	parseLocation(history.location)

	// Reparse the location when the user navigates
	history.listen(parseLocation)

	const html = h(Provider, { store }, h(Main))
	const root = document.querySelector('#main')

	render(html, root)

	// Curry the hotkey string for better performance
	const isClearKey = isHotkey('esc')
	const isConfirmKey = isHotkey('enter')

	const navigateTo = (nextComponent, nextTab) => {

		if (nextComponent == null) return

		location.href = createRoute(nextComponent.id, nextTab.id)

	}

	const clearFilter = () => store.dispatch(setFilter(''))
	const focusFilter = () => document.querySelector('#filter').focus()

	document.documentElement.onkeydown = (e) => {

		const state = store.getState()
		const { components, filter, currentComponent, currentTab } = enhanceState(state)
