It serializes keystrokes instead of pressing multiple keys at a time, allowing the user to press and release a modifier key, such as Shift, Ctrl, Alt, or the Windows key, and have it remain active until any other key is pressed . </P> <P> Sticky keys functionality is available on Microsoft Windows as StickyKeys, on macOS as Sticky Keys, and on Unix / X11 systems as part of the AccessX utility . </P>
