Timeline : The line along the top of the Flash workspace which holds each Frame, from 1 to infinity; allows Flash to display animations frame-by-frame, much like a filmstrip or a child’s “animated” flip book.
Frame : An individual moment in time within the animation; click on any frame in the timeline to see what is happening or displayed on that frame
Keyframe : A special frame where something can be designated to change or happen; i.e., a ball moving left can be told to start moving to the right at a keyframe
ActionScript : The programming language of Flash; version 2.0 uses more natural language and is best suited for beginners and work involving basic kinds of tasks, while version 3.0 is designed for higher mathematical functions
Interaction : Term for any time ActionScript is used to allow the user to do something within the Flash animation, such as stop or start the animation, select a button, or move an object
