There's a key on my keyboard that I have spent most of my typing career learning not to press. Right next to A and right above Shift, it seems impossible to avoid. It MAKES ME SOUND ANGRY when I'm not. It stops many a password from working. And I pretty much never intentionally use it. Caps Lock is just an outdated relic. Why couldn't keyboard designers have had the foresight to put it way up there with F18?
