The Go to and Play Tween action allows you to start a tween playing from a particular frame.
When you create a Tween object you can set the Play Automatically option to automatically start the animation at the frame rate set on the Properties page for that Multiframe. If you do not want this to happen you can deselect this option and use the Go to and Play action to start the tween playing at some other moment in your publication.
Add the Go to and Play action to your trigger, as described in adding actions. The Tween list will automatically appear when you add the action.
Click on the name of the Tween object in the list provided.
Then use the spin buttons in the Go to frame box at the bottom of the panel to set the frame you want to start the tween from.
Note:
The frame does not have to be a keyframe .
Click on the Apply button to save your changes.
