What is an action? An action is simply a set of instructions that executes when a specific event occurs. These events can be a key on the keyboard being pressed, a click of the mouse button, or the movie reaching a certain frame.

In the example I used an instance of a button and placed a mouse event. These mouse events could be when the user clicks on it or rolls the mouse over the button. However you can also have a keyboard key to trigger the action (see our tutorial on keyboard control).

Take a look at the dialog box below. Here you can select the different events (right) that could trigger you actions (left window)

Actions available to the On MouseEvent Command are:
Press Mouse Button Pressed When Pointer is Over Button
Release Mouse Button Released When Pointer is Over Button (Standard Click)
Release Outside Mouse Button Released When Mouse Pointer is Off Button
Roll Over Mouse Pointer Moved Over Button
Roll Out Mouse Pointer Moved Off Button
Drag Over Mouse button Pressed When Pointer is Over Button, Rolled Off the Button, and then the Pointer is Rolled back over the Button.
Drag Out Mouse Button Pressed Over Button then Pointer Rolls Off the Button.
Key Press Occurs when the Specified Key is Pressed.

Note: Assigning an action to an instance of a button will not affect other instances of that button.
