Sticky keys
Accessibility feature
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 ⇧ 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, macOS, chromeOS and KDE Plasma as Sticky Keys (previously stylized StickyKeys on Windows), and on Unix/X11 systems as part of the AccessX utility.
01History
Sticky Keys was first introduced to System 6 as part of the Easy Access extension, which also included mouse keys functionality.
In 1994, Solaris 2.4 shipped with the AccessX utility, which also provided sticky keys and mouse keys functionality.
