Keyboard layouts/localization seem like something went horribly wrong and nobody decided to clean up the mess.

And now we have multiple layouts where the fucking alt key doesn't even work exactly the same between them, how is that even possible? And who thought it was a good idea to differentiate between left and right alt, shift and control keys, leading to subtle issues nobody asked for?

In Vim I made a keyboard shortcut with alt and on the British layout it only works with the left alt key, on the US layout on both. Wat.
