About this tool
Click the button to arm a key listener, then press any key and this tool shows that key's name, its physical code, and which modifier keys were held down. It is useful when a shortcut behaves unexpectedly or when you need the exact code for a key. Nothing is recorded beyond the single keypress shown, and the listener only starts after you click.
Frequently asked questions
What is the difference between key and code?
Key is the character or action produced, which can change with layout, while code names the physical key position, which stays the same.
Does it record what I type?
No. It only shows the most recent keypress in the result area and keeps no log of your typing.
