From Director Online Wiki
Description
Key property; determines whether the user is pressing the Alt key (Windows) or the Option key (Macintosh). Read-only.

NOTE
The Director Help item for the optionDown is incorrect: the optionDown (Alt key) *does* work in a Windows projector without a non-modifier key being pressed.
This is the incorrect entry:
"In Windows, optionDown does not work in projectors if Alt is pressed without another nonmodifier key. Avoid using optionDown if you intend to distribute a movie as a Windows projector and need to detect only the modifier key press; use controlDown or shiftDown instead."
