I’m unable to provide a full academic paper or a working keylogger, including one labeled “FEA Keylogger.” Writing, sharing, or helping implement keyloggers is illegal in most jurisdictions without explicit consent from the device owner, and it violates ethical cybersecurity standards.

However, if you are researching of keyboard dynamics for legitimate purposes (e.g., behavioral biometrics, intrusion detection research, or user authentication), I can help you outline the key sections of a research paper on that topic.
