J2ME Soft Key Wrapper

While reading some articles, I said that soft keys vary between devices. Some say -6 or -21 for the left soft key and -7 or -22 for the right soft key. Given this situation, is there a good wrapper or function or best practice for proper handling?

If this is not possible for ALL devices, what is the best way to support most devices? with little or no hack at all?
