About:
Showkey is a command-line utility that displays keyboard input in real-time, showing both the ASCII values and keycodes of each keystroke. It is particularly useful for debugging terminal behavior, identifying key sequences, and understanding how different terminals handle input. The tool provides immediate visual feedback, making it invaluable for developers and system administrators working with keyboard mappings.
Key Features:
  • Real-time keystroke display with ASCII and keycode values
  • Supports special keys and escape sequences
  • Lightweight and simple command-line interface
  • Helpful for terminal debugging and input analysis
Use Cases:
  • Debugging keyboard input issues in terminal applications
  • Identifying escape sequences for custom key bindings
  • Learning how different terminals interpret key presses
Alternatives:
  • showkey – Built-in Linux utility with similar functionality but different output format
  • cat -v – Basic input display but lacks specialized keyboard debugging features
