Is it possible (softwarewise) to put different functions to keys? For example, if I would like to change "up arrow" to be Ä, would that be possible? Or if I change device (Android) language to Finnish will it somehow affect HW keyboard functionality?

EDIT: in a Finnish IO-Tech.fi forum a developer (with experience about these type of things: https://android.onse.fi/finqwerty/ ) has said that he can add scandic layout support for the keyboard if "manufacturer has not prevented it". I would assume that f(x)tec people would not prevent this so hopefully scandic layout support should be possible.
