Sticky Keys is a long-running Windows accessibility feature designed for people who cannot easily hold down several keys at once, allowing Shift, Ctrl and Alt to be pressed one at a time. The prompt appears after Shift is pressed five times, a shortcut many PC gamers hit accidentally while sprinting or crouching in games. That accidental trigger turned the notification into a running joke online, where creators reuse the chime to mark moments of panic, distraction or poor keyboard control in gameplay videos, reaction edits and short comedy clips.
