I bought a Chuwi pro notebook that comes with an American standard keyboard and I use it to type in Spanish and Portuguese. so I had to adapt it to my work. What I did:
1 – in settings I put Spanish language and in keyboard (advanced settings) I put the same, keyboard in Spanish
2 – I bought some keyboard stickers (you can find them on Amazon)
3 – The Ç I put in the key next to End works for Ç and for ç, automatically
4 – The circumflex will work on the a key with the alt gr key
to the right of the P, com shift
5 – acute accent will work on the key to the right of the Ñ
6 – the tilde will work on the 4 key, with alt gr
7 – @ will work on the 4 key, with alt gr
8 – the backslash will work on the key to the right of nr 1 with alt gr
9 – to the left side of the Ç, with alt gr will work]
And that’s it … the other keys will work according to their printed symbols.
You can now work in both languages with the absence of only the key symbol that curve, which I don’t use and that’s it! I hope with that I have helped at least those who work with notes Techlast or Chuwi pro and need to write in Portuguese.
