I am curious why most keyboard constants are not recognized and a few are.  
Code:  
// runs fine, outputs 37  
import flash.ui.Keyboard;  
trace(Keyboard.LEFT)

Code:  
// Does not compile, but is offered as a choice for auto-complete! Should output 65  
// ERROR: 1119: Access of possibly undefined property A through a reference with static type Class.  
import flash.ui.Keyboard;  
trace(Keyboard.A)

Working with Flash CS4. Any ideas?
