guides to align the movie clip to the top and left edges of the GPS screen.

5. With the instance of map_skewed selected on the Stage, type screen_mc in the Instance Name

Flash is designed to present code hints when you name your instances with the
appropriate suffix:
■ When naming a movie clip instance, always give the instance a suffix of _mc, as
in screen_mc.
■ When naming a button, use the _btn suffix.
■ When naming a text field, use the _txt suffix.
Note: For more information about additional instance name suffixes that prompt code hints, see
“Writing code that triggers code hints” in Using ActionScript in Flash.
