Question about Razer BlackWidow Chroma V2

If I am not mistaken, this is only possible in a very awkward way. By pressing "Shift" + " + "a" at the same time, a small "ä" can be written. Alternatively, via an Alt code, i.e. by pressing "Alt" and successively the numbers 1, 3 and 2. To write a capital "Ä", the caps lock key should be activated beforehand. Using the Al code, it should be "Alt" and the numbers 1, 4 and 2.

I hope someone knows a more "comfortable" method.
Kind regards :)
