KeystrokeRecorder X is an application that records each keystroke into a file for later retrieval.
Installation is much simpler than previous versions of KeystrokeRecorder as it is now a simple background, also known as faceless, application. Just copy KeystrokeRecorder X to you hard drive and double click it.
Since it is a background application it might not appear to that it launched. Just press some keys on your keyboard and you'll see the results in the log file.
