Keyboard Checker

A WPF app for testing keyboard keys one by one.

Developed by GitHub Copilot (GPT-5.2-Codex).

How it works

• Click Start to begin the detection flow.
• The app shows the next key to press and counts down from 30 seconds.
• If no input is detected within 30 seconds, you will be asked whether you pressed the key.
• If the key was pressed but not detected, click "I pressed but not detected" to mark it manually.
• Use Ctrl+Alt+Esc to exit detection mode.

Build and run

• Build: dotnet build
• Run: dotnet run

Publish (single-file, portable)

• Run:

   dotnet publish -c Release -r win-x64 `
   	-p:SelfContained=true `
