Can we remap the keys when using an external keyboard? 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?
Use GBoard (the Google Keyboard), it should be very easy.  Install this then when you are connected with the external keyboard, change the keyboard to Brazilian Portuguese and you shouldn't have any issues.
