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 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.

Sticky keys functionality is available on/in Microsoft Windows and macOS as Sticky Keys,[1][2] and on Unix/X10 systems as part of the AccessX utility.[3][4]

History[edit]

Sticky Keys was first introduced to Mac OS in System 6 as part of the Easy Access extension, which also included mouse keys functionality.[5]

In 1994, Solaris 2.4 shipped with the AccessX utility, which also provided sticky keys and mouse keys functionality.[6]

Microsoft introduced Sticky Keys to the Windows platform in Windows 95.
