In the Shortcut field, type the name of the keyboard shortcut, using the following conventions:
•
Spell out key names, such as Control or Alt.
•
Use capital letters for alphabetic characters.
•
Use a plus sign (+) between key names, with no spaces (for example, A).
Important:
Flash does not check that the ActionScript to code the keyboard shortcut was created.
Map 7 to myButton instance
1
Select the object on the Stage, display the Accessibility panel, and in the Shortcut field, type
7
.
2
Enter the following ActionScript 2.0 code in the Actions panel:
function myOnPress() {
trace( "hello" );
}
function myOnKeyDown() {
if (Key.isDown(Key.CONTROL) && Key.getCode() == 55) // 55 is key code for 7
{
Selection.setFocus(myButton);
myButton.onPress();
}
}
var myListener = new Object();
myListener.onKeyDown = myOnKeyDown;
Key.addListener(myListener);
myButton.onPress = myOnPress;
myButton._accProps.shortcut = "Ctrl+7"
Accessibility.updateProperties();
Note:
The example assigns the 7 keyboard shortcut to a button with an instance name of myButton and makes
information about the shortcut available to screen readers. In this example, when you press 7, the
myOnPress
function displays the text “hello” in the Output panel. See addListener (IME.addListener method) in ActionScript 2.0
Language Reference.
