Sticky Keys is an accessibility feature that modifies the input behavior of modifier keys—specifically Shift, Ctrl, Alt, and the Windows/Command key. When activated, these keys remain "stuck" in a pressed state until a subsequent key is pressed, allowing for one-handed operation of complex shortcuts.

Under normal circumstances, a shortcut like "Ctrl + S" (Save) requires the user to hold the Control key while tapping the S key.

“Sticky Keys” is a fundamental accessibility feature found in most modern operating systems. Designed to aid users with physical disabilities or ergonomic limitations, it allows users to execute keyboard shortcuts (such as Ctrl+C or Alt+Tab) by pressing keys sequentially rather than simultaneously. This paper provides an overview of the feature’s history, technical utility, activation methods, common troubleshooting scenarios regarding accidental activation, and its broader impact on human-computer interaction.
