Sticky keys is an accessibility feature of some graphical user interfaces to assist users who have physical disabilities or help users reduce repetitive strain injury (or a syndrome called the Emacs Pinky). It essentially 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.
Microsoft introduced StickyKeys to the Windows platform in Windows 95.
To enable this shortcut, the Shift key must be pressed 5 times in short succession. This feature can also be turned on and off via the Accessibility icon in the Windows Control Panel.
To turn off once enabled, just simply press 3 or more of the Sticky Keys (Ctrl, Alt, Shift, Windows Button) at the same time.
Over the years, this feature has posed difficulties for users who use the Shift key heavily, such as gamers, because an activation popup will be placed above all other applications, disturbing their gameplay. This can be fixed by going into the control panel and going into the accessibility option and then disabling the shortcut option. The feature creates a vulnerability in some versions of Windows, enabling the recovery or replacement of the user password using a method known as a Sticky key attack.
Sticky Keys makes an alert sound on Windows computers and laptops, but on Mac or Apple computers, it makes a quiet tapping sound. On Mac, Sticky Keys is pressed only once on the shift key.
