Can you find the [ and ] keys? If you’re having trouble, it’s because you have to use 2 (two!) modifier keys and activate the ( or ) keys, which themselves are clumsily placed. This cannot be typed one-handed in a comfortable way. Apple’s azerty layout is unique in this, as regular azerty puts those keys in a more sensible place. I keep wondering: why does apple make me do a Vulcan nerve pinch every time I want to index an array?
