The key no one EVER bloody fucking uses. This key is normally ignored by morons, imbeciles, ignorants, dumbasses, shitbirds, and all around -twats-.
Morons that ignore this beautiful key, often forget many other, wonderful, things you can do with a keyboard.
People on the internet often come back with a big, bullshit argument based on the 'fact' that no one bother to type things correctly on the computer because its a waste of time.
Well you know what, shitbird? If you learn how to type, and practice good grammar, punctuation, and spelling, eventually typing like this on the computer is easy. I, personally, think writing "omfglaewlers, 1 jst t0k @ sh1t! LOL!"
