Sticky Keys is a long-standing accessibility feature in Microsoft Windows that lets users press modifier keys such as Shift, Ctrl and Alt one at a time instead of holding them down together. Pressing Shift five times in quick succession activates the feature and triggers its distinctive alert sound, which is why many people recognise it from accidental activations rather than deliberate use. Online, the clip has become shorthand for computer mishaps, keyboard frustration and unexpected popups, keeping it useful in gaming videos, reaction edits and tech humour long after most viewers first heard it.
