All symbols have their own timelines. Button symbols have a timeline that
only contains 4 frames. each frame represents a different “button state.”
Button States
State
Description
Up
The Up keyframe holds artwork that defines what
the button looks like before the user’s mouse does anything with
the button
Over
The Over keyframe is what the button looks like
when the user positions the mouse over the Hit area of the button.
This is also referred to as the rollover state of the button.
Down
The Down keyframe defines what the button looks
like when it is clicked. This state is usually seen for only a split
second, but it can be seen for longer periods of time if the user
holds down the mouse.
Hit
The Hit keyframe of the button is always invisible
to the user. It defines the area of the button that is reactive to
the mouse. This is what makes the button clickable.
