Developer Builds Zero-Hardware Keyboard Light Using C# and WPF

A developer created LightBar For Keyboard, a Windows app that uses the monitor as a light source to illuminate keys without physical hardware. The app leverages the Windows AppBar API to dock a reflective light bar at the screen bottom, pushing maximized windows upward. It includes an OLED efficiency mode that uses a dark bar with white text to reduce power consumption on OLED displays.
