I would like some help, if possible of course.
I'm Brazilian and I used the standard keyboard “ABNT2” for many years.
Recently I chose to buy a keyboard for its excellent quality. The default for this keyboard is “ANSI”.
My adaptation with the new keyboard was excellent and I didn't have any problems. As I have been a FastKeys user for some time, I thought about the possibility of remapping some keys that could help my typing speed.
For example, I was able to remap the following keys on the “ANSI” keyboard perfectly:
1) ’ ;: ’ = ‘ç ’
2) 'ALT + ' / ? ’ = ‘ º ’
3) 'ALT + ' ] } '= ' ª '
(I use the characters above a lot)
But I had trouble remapping the ' " (ANSI) key to ^ ~.
For example: On the ANSI keyboard I would like to write the word EXECUÇÃO by typing the key sequence: E – X – E – C – U - ; : - ‘ “ A – O
My remapping generates the following word: EXECUÇÃÓ
Could the noble colleagues help me with the possibility of remapping the keys of the ANSI keyboard below to work in the same way as the ABNT2 keyboard?
1) ` ~ = ' "
2) ' " = ^ ~
I believe this is not possible due to some technical issues, but as I am a noob at FastKeys I'm leaving the question here for the more experienced.
Thanks.

Marcelo.
