This great little utility was written by the same Korean keyboard god that also developed the LIMKB keyboard controller.
The program lets you check to see if all keys on your board function properly - it can also be used to check for ghosting and/or nkey rollover support testing.
Unlike ALL other keytest applications that I have tested (including commercial ones like PassMark KeyboardTest) this one is not tricked by fake strokes and checks only the real signals sent from your keyboard. What does this mean? This means that scripts and macro programs like AutoHotKey or AutoIt which generate keystrokes using the Windows API do not get picked up. In fact I am curious to know how he tells these apart from real keystrokes - like I said before all other programs fail at this and also pick up the "fake" keystrokes.
