onKeyUp = function() {}
Invoked when a key is released. The onKeyUp event handler is invoked with no parameters.
You can use the Key.getAscii() and Key.getCode() methods to determine which key was
pressed. You must define a function that executes when the event handler is invoked. You can
define the function on the Timeline or in a class file that extends the MovieClip class or is
linked to a symbol in the library.
The onKeyUp event handler works only if the movie clip has input focus enabled and set.
First, the MovieClip.focusEnabled property must be set to true for the movie clip. Then,
the clip must be given focus. This can be done either by using Selection.setFocus() or by
setting the Tab key to navigate to the clip.
If Selection.setFocus() is used, the path for the movie clip must be passed to
Selection.setFocus(). It is very easy for other elements to take the focus back after the
mouse is moved.
Example
The following example defines a function for the onKeyUp method that sends a trace()
action to the Output panel:
my_mc.onKeyUp = function () {
trace ("onKey called");
}
The following example sets input focus:
my_mc.focusEnabled = true;
Selection.setFocus(my_mc);
