Typing Mirandese Characters
Mirandese is written in a variation of the Latin alphabet that includes the letter ç. Mirandese also uses characters with diacritic marks, including á, ã, é, ê, í, ó, ô, and ũ, to indicate stress, nasalization, and various other aspects of pronunciation. There are two methods for typing these characters.
The simplest method is to use the character suggestions. To do so, type the base character for the letter you want, then select the special character from the set of characters which appears.
The other method is to use the virtual keyboard with the layout set to Mirandese. (If necessary, you can change the layout by clicking 
and selecting an option in the Keyboard Language menu.)
Locate the character you want on the virtual keyboard, then click on it or press the corresponding key on your physical keyboard. Capital letters and certain punctuation marks, such as the question mark, are available by holding down the Shift key. Many of the special characters are available by holding down the Ctrl and Alt keys at the same time.
See Typing Accents and Special Characters for details on both typing methods.
