showkey for Mac

showkey is a simple key visualization tool that runs from the command line, suited to users who need to observe keyboard input. It displays pressed keys in real time, helping you confirm whether a particular key is correctly recognized by the system, or providing an intuitive reference when debugging keyboard or terminal input issues. For developers, system administrators, and users who enjoy tinkering in the terminal, this kind of small utility is straightforward to use, requires no complex configuration, and lets you observe key presses as soon as it runs. It does not pursue a flashy interface, focusing only on presenting key information clearly, and belongs to the category of practical tools that seem unremarkable day to day but prove useful when needed.
