Which term refers to the actions that make a program responsive to user input?

The term that refers to the actions that make a program responsive to user input is "Events." In the context of programming and animation, events are specific occurrences that happen in the system, such as mouse clicks, keyboard presses, or any other types of user interactions. When users interact with a program, those interactions trigger events that the program can respond to.

For instance, in Adobe Animate, when a user clicks a button, it generates a click event. This event can then be connected to actions or functions that execute in response, such as playing an animation or navigating to another scene. Events serve as the bridge between user input and the program's behavior, allowing developers to create interactive experiences.

The other terms listed, while related, do not specifically encapsulate the concept of user input responsiveness. User commands refer more broadly to instructions given by users, actions can describe any behavior executed but do not necessarily relate to user input, and functions are reusable pieces of code that perform tasks without directly signifying interaction or responsiveness to user actions. By focusing on events, developers can build dynamic and engaging applications that effectively respond to user engagement.
