Keyboard Shortcut Identifier FAQ

Common keyboard shortcut identifier questions

What is the keyboard shortcut identifier?

The keyboard shortcut identifier tells you what any key combination does. Press a key or combo and it displays the keys as realistic keycaps and explains what that shortcut triggers on Windows, macOS, and Linux, using a database of over 120 common shortcuts.

Does it show shortcuts for all operating systems?

Yes. Choose your operating system to see the primary action, and the identifier also lists what the same combination does on the other systems, so you can translate shortcuts between Windows, macOS, and Linux.

What happens if my shortcut is not recognized?

Combinations outside the catalogued database show a clear notice that the shortcut is not in the database. If you think a common shortcut is missing, you can suggest it through the site feedback link.

Is the keyboard shortcut identifier private?

Yes. Key presses are matched against a JavaScript database that ships with the page, so everything runs locally in your browser and no keystrokes are sent to a server. The tool is free with no download.
