Key Press Replay is a Windows tool that automates keyboard input. You write a list of keystrokes in a simple configuration file, and the app replays them over and over in a loop. It is designed for situations where you need to repeat the same sequence of keys in another program, whether that is refreshing a page on a timer or running a repetitive shortcut in a specific application. To use it, you download the program, create a text file that defines your key sequence, and launch the executable. Windows will ask for administrator permission, which is required because the tool needs to send keystrokes to other programs that might also be running with admin privileges. After the program starts, you get a brief window of time to click on whatever application you want the keys sent to. The tool then presses the keys you defined, in the order you defined them, and loops back to the beginning when it finishes. You stop it anytime by pressing Ctrl+C in the console window. The configuration is straightforward. You specify how many times to repeat the sequence, an initial delay to give yourself time to switch windows, and an ordered list of actions. Each action names a key or key combination like F5, Ctrl+S, or Ctrl+Shift+S, how long to hold the key down, and how long to wait before the next press. The format supports standard letters, digits, function keys, arrows, punctuation, and modifier combinations, so it covers most keyboard inputs you would normally type by hand. This is useful for anyone who needs to automate repetitive keyboard tasks on Windows. A tester might use it to cycle through screens in an app by repeatedly sending Tab and Enter. A developer could set it to hit F5 every few seconds to keep a dashboard refreshed. Someone working with software that requires periodic input could configure a sequence to keep a session active or trigger a shortcut on a schedule. The project is built specifically for Windows and relies on built-in operating system features to simulate input, so it is not a cross-platform tool, but within that scope it handles both simple taps and long key holds.
