        // Graceful exit necessary to unhide cursor
	done := make(chan bool)
	listenForExitSig, cleanup := ts.InitExitStrat(done)
	go listenForExitSig()

        // up() traverses list up
        // down() traverses list down
        // current() gets current active index
	up, down, current := ts.InitRender(items)

        // Read from stdin without buffering
	stdin := make(chan string, 1)
	go ts.ReadStdin(stdin)

readInput:
	for {
		select {
		case <-done:
			break readInput
		case ch := <-stdin:
			switch ch {
			case "k":
				up()
			case "j":
				down()
			case "\n": // Enter
				fmt.Printf("You've selected %s\n", items[current()])
				break readInput
			}
