how to improve spell checking?

hello.

I'm having a hard time with the Mac OS spelling checking... is simply awful.

I'm always swiping from portuguese to english.... the auto-detect is horrible, is very rare to detect errors, and when detects... the suggestions are none or useless.

What makes my problem worse is that portuguese is very similar to spanish, so it happens a lot I made a mistake, but is not detected because is a spanish word.

How can I improve this? If only possible inside chrome/safari, will be more than enough.

best regards,

 

meanwhile I made some progress:

If I'm going to the menu:

Language & text -> text

And instead of "Automatic by language" I choose manual a language, it works properly and I would expect.

The problem, however, continues, can I use automador, some service, to easily change the language ?

Like I press two bottoms and the spell checking the language from EN to PT and backwards.

tks in advance.
