Scanning for up and down arrow in Go?

Question

I'm trying to scan for the up and down arrow key codes in Go, but it doesn't seem to be working. So far I've tried this:

in = bufio.NewReader(os.Stdin)
b, err := in.ReadByte()
fmt.Println("Key code:", b, err)

But when I press the up or down key, it never stops reading (it never run the Println statement) and just displays "^[[A" and "^[[B" directly in the terminal. Any idea?

I'm fairly certain you can't get raw mode input easily without os syscalls. Have a look at the answers to Read a character from standard input in Go (without pressing Enter) .

It seems that the generally accepted solution is to use termbox-go which apparently has fairly good cross platform capability.
