Navigate Html Button Reponse using the keyboard

[einGlasRotwein]

Hi everyone,

I am trying to make the html button response plugin respond to keyboard input. Ideally, I would like participants to press the arrow keys to switch from button to button (i.e. if they press the right arrow, the button one position to the right is highlighted, if they press the left button, the button one position to the left ist highlighted etc.), and then confirm they selection with another key.
I thoight I can solve this by adding an event listener to on_load, but that does not work. (In my initial attempt, I just want the event listener to print "left" or "right" to the console, depending on which key was pressed, but not even that is working.)

Here is the code I tried to add to on_load:

    document.addEventListener("keydown", (e) => {
      if (e.key === "ArrowLeft"){
        console.log("left!")
      } else if (e.key === "ArrowRight"){
        console.log("right!")
      }
    })

Does anyone have a clue where/how to best add the event listener? Or a better idea how to approach the problem?

Thanks in advance!

Okay, never mind, I was very stupid. The event listener works fine, I was simply editing the wrong script.
I doesn't seem like I can close my own issues (sorry if I overlooked something).
