|Version:||WCAG 2.0 and up|
Changing the setting of any user interface component does not automatically cause a change of context unless the user has been advised of the behavior before using the component.
The purpose of this success criterion is to ensure that users do not trigger unexpected actions that change the context (e.g., submitting a form, spawning a new window, changing focus to another element, changing the text) when they input values.
Not all users can perceive that the context has changed, or they may have difficulty keeping track of such changes.

If a change of context must occur, authors need to ensure that users are informed of the actions before inputting information.
