How to use accents on a bluetooth keyboard?

[heitoor]

Hello, i am from brazil and my natural language is portuguese. So, we have a lot of words with accents.

I am using apple keyboard with my dex, but i can use accents like i use in my notebook.

I tried to configure the keyboard, with no success.

Is there a way to do that? Should i buy another keyboard or theres some apps that correct this?

*Sorry my grammar

Thank you all
