Sticky keys
Sticky keys is an accessibility feature of some graphical user interfaces which assists users who have physical disabilities or helps users reduce repetitive strain injury. It serializes keystrokes; instead of being required to press multiple keys at a time, the user can press and release a modifier key, such as , , , or the , and have it remain active until any other key is pressed.
Sticky keys functionality is available on/in Microsoft Windows, macOS, chromeOS and KDE Plasma as Sticky Keys,[1][2] and on Unix/X11 systems as part of the AccessX utility.[3][4]
On Microsoft Windows operating systems, it has been commonly used as a exploit to get SYSTEM account priviliges on Windows versions since 2000. By replacing the sethc.exe file in System32 with cmd.exe (the command prompt) you can click shift five times on any screen and get a command prompt.[5]
History
Sticky Keys was first[when?] introduced to System 6 as part of the Easy Access extension, which also included mouse keys functionality.[6]
In 1994, Solaris 2.4 shipped with the AccessX utility, which also provided sticky keys and mouse keys functionality.[7]
