My computer is an Apple MacBook and the OS is Snow Leopard. Hope that helps. I already know the keystrokes to make the
accent and
tilde, I just can't find out which keystroke will give me an upside-down question mark. I need it for more than just writing on this forum.
Okay, I found it (eureka!)
¿ = Opt + Shift + / (
Option plus
Shift plus
Forward slash)
Here are some more for free
accent - Opt + E (Ex:
Tú)
tilde - Opt + N (Ex:
Baño)
