A Windows Forms utility called Hotkey Typer simulates human-like typing of predefined text snippets using a global hotkey (CTRL+SHIFT+1). Built with .NET 10 and GitHub Copilot assistance, it uses Windows API P/Invoke for hotkey registration and SendKeys for character-by-character input with randomized delays. The app persists settings to JSON, runs in the system tray, and includes adjustable typing speeds. Ideal for recording demos and tutorials where manual retyping or clipboard pasting would be disruptive. Source code is available on GitHub, and similar functionality exists in ZoomIt/PowerToys.
