history
Project history and usage
Key Codes is a free macOS inspection utility that reports the Unicode value, key code, and active modifiers for typed keys.
Project history
Many Tricks developed Key Codes as a free macOS utility for displaying the Unicode value, virtual key code, and modifier state of keyboard input. Version 2.0 brought Retina support, a persistent history view, and direct-edition updates through Sparkle; later releases added modifier breakdowns, Apple-silicon support, dark-mode improvements, and web-hosted help.
Adoption history
Many Tricks has offered Key Codes as a free utility both directly and through the Mac App Store. Its narrow focus made it a convenient diagnostic tool for Mac developers and users investigating keyboard events.
How it is used
A user opens the application's single log window and presses keys or key combinations. Key Codes reports the resulting character, key code, and modifiers; optional controls also track key-up events and modifier-state changes.
Why package nerds care
Key Codes is the sort of small, single-purpose macOS diagnostic utility favored by package collectors: it exposes low-level keyboard-event information without requiring a custom test program. Many Tricks also made the source available for developers to inspect.
