You don't need external dependencies to achieve this.You can use a channel and set a timeout on it.

import (
"bufio"

"log"
"fmt"

var reader = bufio.NewReader(os.Stdin)
func readKey(input chan rune) {
char, _, err := reader.ReadRune()
if err != nil {
log.Fatal(err)
}
input <- char
}
func main() {
input := make(chan rune, 1)
fmt.Println("Checking keyboard input...")
go readKey(input)
select {
case i := <-input:
fmt.Printf("Input : %v\n", i)
case <-time.After(5000 * time.Millisecond):
fmt.Println("Time out!")
}

s.Println()
gc.Echo(false)
