An Alt Code is a number, or series of numbers that when pressed in conjunction with the Alt key produces a cute little symbol like a heart or smiley face.
You can use ’em on Facebook to show some love or just to spruce up your status updates. Alt+1, Alt+2, Alt+3, Alt+4, Alt+5, etc.
Remember, you can only use the number pad to type in the codes, though. The line at the top of your keyboard won’t work.
