What is ¡?
Like that guy said, it's an upside down exclamation mark. And the only reason he only has to press alt + 1 is because he has a <Mac> keyboard. I'd know because I used to have one. Now think to yourself. Is it REALLY worth owning a Mac, in order to save pressing a few extra keys? As one person who's name I seldom remember, a Mac is like a car which is only compatitable with like, 5% of roads. It' s nothing worth bragging about, pal. I'd rather have an 'anal' keyboard.
of course, he could just have a better keyboard.
An upside-down exclamation mark.
For my keyboard, it is Alt + 1
I doubt your anal keyboard does it.
