This question already has an answer here:
I'm using my physical keyboard on my tablet with Android. The Brazilian keyboard works fine for me, there are only two problems:
The right-shift is "/" instead of shift.
The "ˆ" is different and is not accepted by LaTeX. (In LaTeX, we use aˆb for exponetiation and this one doesn't work).
One possible fix is to be able to remap the keys, Is this possible? Is there some app that allows me to remap the keys?
