Use

Processing user input and executing commands:

func testInput() (err error) {
	var (
		data = goinput.Data{
			Slice: make([]byte, 32),
		}
		input = &goinput.Input{
			Fd: syscall.Stdin,
		}
		sigInt = make(chan os.Signal, 1)
		keys   = goinput.Keys{
			"a": {
				EventFunc: func(key *goinput.Key) (err error) {
					fmt.Println("a")
					return
				},
			},
			"c": {
				EventFunc: func(key *goinput.Key) (err error) {
					key.Data[0].(chan os.Signal) <- syscall.SIGINT
					return
				},
				Data: append(make([]any, 0, 0), sigInt),
			},
			"1 2 3": {
				EventFunc: func(key *goinput.Key) (err error) {
					fmt.Println("1 2 3")
					return
				},
			},
		}
	)

	defer func() {
		close(sigInt)
	}()

	if err = keys.Compile(); err != nil {
		return
	}

	signal.Notify(sigInt, syscall.SIGINT)

	for {
		var (
			pressedKeys = keys.PressedKeys()
			pairNum     = 0
		)

		if !input.IsRaw() {
			if err = input.SetRaw(); err != nil {
				return
			}
		}

	_loop:
		if err = input.Read(&data); err != nil {
			return
		}

		for _, name := range *pressedKeys.Update(keys, data, pairNum) {
			switch key := keys[name]; {
			case pairNum == key.Len()-1:
				if err = input.ResetRaw(); err != nil {
					return
				}

				key.Event()

				select {
				case <-sigInt:
