that you select Control > Disable Keyboard Shortcuts so you can change focus between the
two fields using Tab.

currently has focus, the method returns -1. Selection span indexes are zero-based (for example,
the first position is 0, the second position is 1, and so on).

Example
The following example creates a text field at runtime, and sets its properties. A context menu
item is added that can be used to change the currently selected text to uppercase characters.
this.createTextField("output_txt", this.getNextHighestDepth(), 0, 0, 300,
200);
output_txt.multiline = true;
output_txt.wordWrap = true;
output_txt.border = true;
output_txt.type = "input";
output_txt.text = "Enter your text here";
var my_cm:ContextMenu = new ContextMenu();
my_cm.customItems.push(new ContextMenuItem("Uppercase...", doUppercase));
function doUppercase():Void {
var startIndex:Number = Selection.getBeginIndex();
var endIndex:Number = Selection.getEndIndex();
var stringToUppercase:String = output_txt.text.substring(startIndex,
endIndex);
output_txt.replaceText(startIndex, endIndex,
stringToUppercase.toUpperCase());
}
output_txt.menu = my_cm;
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth() method.
