What is the purpose of the Sticky Keys feature in X?

 The Sticky Keys feature in X is an accessibility option that allows users to press modifier keys (such as Ctrl, Alt, Shift, or the Windows key) one at a time, instead of holding them down simultaneously, to perform keyboard shortcuts. For example, to copy something, a user can press Ctrl, release it, and then press C, instead of pressing Ctrl+C together. This can be helpful for users who have difficulty pressing multiple keys at once, or who prefer not to do so. References:  https://www.howtogeek.com/739764/how-to-turn-off-sticky-keys-on-windows-10/
