I use an Azerty keyboard. How can I handle keybindings easily?

"Alt + Shift" keyboard shortcut is your friend.

It does "set your entire computer to qwerty". But it's easy and quick enough to swap between "azerty" and "qwerty" that it shouldn't bother you much.

But if you have to write ingame ... Then I know no other option than rebinding, and if you can't, you're stuck.
