About Spanish letters
Spanish needs only the acute accent, the ñ and the ü, plus the inverted ¿ and ¡ that open questions and exclamations.
The Spanish and Latin American layouts put ñ to the right of L. With US-International on Windows, ~ then n gives ñ and Alt Gr+? gives ¿.
On a Mac, Option+N then N types ñ; Option+Shift+? types ¿ and Option+1 types ¡.
