Here we learn how to insert secret symbols from your keyboard onto Facebook or any other regular program. This only works on PCs, sorry Mac users! By holding down the alt key and pressing numbers on the keypad from 1-9 and beyond, we discover there are many different symbols that pop up. There are smiley faces, arrows, numbers, punctuation marks, and various other random symbols. Exploring these on your own is simple and will show you everything there is to choose from. You can get creative with these symbols if you choose, even incorporating them into your own name and different words for emphasis or flare.
