Hey ​@Marllony De Paula, thanks for reaching out and apologies for the delayed reply! 

I don’t speak Portuguese, so I hope it is ok that I reply in English. 

Can you please confirm that you’re using the correct keyboard layout? 

From the Help and resources ? icon in the lower, right-hand corner of your file, select Change keyboard layout… 

From there, select the correct Keyboard layout from the drop-down menu. This should fix any keyboard shortcut issues you’re experiencing.
