I need a new keyboard but the QWERTY version is a lot cheaper than the AZERTY version. Is it possible to just change the keys of the QWERTY keyboard and make it an AZERTY keyboard?
The keyboard that I like is mechanical btw 


how can u take the caps of do u need like a special tool for it or?ah, wasnt aware they had all of those changed as well. looking at a diagram between the two...
as far as getting the keyboard to function, should be possible. however given that they provide the icons on different keys totally than qwerty you wont be able to have the correct icons on the correct keys (for symbols... for letters you would be fine).
if you bought a well known keyboard you might be able to get keycaps cheaper than an azerty version. perhaps take a look for caps.
