## Overview

This small Go program captures terminal keystrokes, writes each rune to `test.txt`, and displays the pressed key. Pressing Escape ends the loop; deferred cleanup closes the keyboard and file. The source confirms terminal capture and file output, but does not establish global capture or any of the README’s proposed future features.

Main entry points: [`keyLogger.go`](https://github.com/mystigan/keylogger/blob/master/keyLogger.go) (Key logger)
