[Q] external keyboard: set custom modifier key
I'm searching for a external keyboard for my android-stick. My big problem is those which fits my needs are in QWERTY-layout, but I'm from Germany and therefore would like to be able to type umlauts (ü, ö, ä, ß).
Because many of the keyboards designed for Android don't have ctrl or alt keys, my idea was to define a custom modifier key, like the space bar for example, so that when I press space+a it would result in ä.
Is this even possibe with Android?
