Invented by greeting card companies to fill the void between Trafalgar Day and Mole Day, Caps Lock Day is the one occasion when lovers of capitalization can come together with the haters from CAPSoff and hack-a-day and pay homage to the little key that habitually blows up your spot when trying to type a lower-case ‘a.’

ALSO THE KEY THAT MAKES LONG BLOCKS OF COPY HARD TO READ. THE KEY THAT IS INTERPRETED BY NETIQUETTE AS SHOUTING. THE KEY THAT PEOPLE WHO AREN’T GOOD TYPISTS EMBRACE.
