Spanish keyboard layouts have dead keys. For instance, to type the above “ó”, one would press the diacritic mark key (´), release it and press the base “o” afterwards. Both circled in green in the image below.
But no previous dead key is pressed to type “ñ”, as it has its own key. Circled in red in the image.
I use the wireless Logitech keyboard with Spanish layout in this image.
What is the “help vault”?
