Add delay for key input?

[Jason1923]

Hi, I'd like to map a key to a button on a GameCube controller, except it should have a slight delay before being pressed. I want this so I can input, for example, Y → 0.5 second pause → X upon pressing the "K" key on my keyboard. Is this possible? I have been experimenting with the timer() function, but that doesn't seem too precise and it's not really made for my use case. Thanks!
