What does "mouse event" refer to in terms of user interaction?

The term "mouse event" specifically denotes interactions that involve the mouse, such as clicking, dragging, and hovering over elements on a screen. In the context of user interaction in applications like Adobe Animate, mouse events allow developers to respond to user actions in the interface.

When a user clicks on an object, drags it around, or hovers the pointer over a clickable area, those actions generate mouse events that can be captured and handled by the application to execute specific behaviors or animations. This is crucial for creating interactive content, as it enhances user engagement and provides a dynamic experience.

The other options pertain to different forms of user interactions. Touch gestures, for example, involve actions performed on touch-sensitive devices, whereas keystrokes relate to keyboard input. Scheduled tasks in the timeline refer to animations and actions that occur at predetermined times rather than in response to direct user actions. Thus, they do not fit the definition of mouse events.
