Proper keyboards group in clusters F1–F4, F5–F8, F9–F12, with gaps between them. Unfortunately, this practice is regularly disregarded (even though uniformity is obviously a terrible idea), and particularly uncommon on laptop keyboards.

I probably still wouldn't be able to hit them accurately, I'm not a great typist :) fn+h/j/k/l isn't mapped to anything, these keys are much more accessible and switching windows is probably the thing I do most, so it seems to make sense to me
