A default select works with combinations using the latest Firefox and Chrome - see https://jsfiddle.net/0kcbnfd2/

It could be a case of custom controls being poorly implemented.

It's why I always recommend against non-native controls by default, whether on the web or desktop/mobile - even if you're particularly observant about your platform (and most devs aren't), there's probably still a bunch of little things like these that you'll miss and won't implement, and that people actually use daily.

And not only that, but unless you're observant about literally every platform on which your app will run, you are bound to break something, whether subtly or majorly.

I thought it wasn't working, but apparently on FF you have to do it really fast. Take a second between key presses and it'll just revert to the old behaviour. Talk about being shitty to people with poorer motor control or who need to hunt and peck.

Now that's how it always should've worked.

Have you tried typing N multiple times? My go to method is typing I six times to get me to Ireland and it usually works.

What OS do you use? Linux apps do what your parent comment describes, and from memory, Windows apps do what you describe.
