Keyboard Shortcut Identifier
Press any key combination to see what it does on Windows, macOS, and Linux.
Press any key combination
Try Ctrl+C · Ctrl+Shift+T · Alt+Tab · Win+E
How to use
- Click inside the large bordered stage so it has keyboard focus (you should see the focus ring).
- Confirm Your OS — Windows, macOS, or Linux (auto-detected on load, or tap another pill to override).
- Press a shortcut (e.g. Ctrl+C, Cmd+V on macOS). The captured keys appear as labeled chips.
- Read What it does on the selected OS; expand On other systems when cross-platform entries exist.
- If you see Shortcut not in database, the combo is not in the built-in catalog (it may still work in apps).
- Click Reset to clear chips and the last lookup, then focus the stage again for another combo.
FAQ
Why did nothing match?
Only combos in the local shortcut database resolve; many IDE or game binds are app-specific.
Does this block my real shortcut?
The handler calls preventDefault in-page — be careful using destructive shortcuts while focused here.
Is data sent online?
No. Matching uses a local lookup table bundled with the app.
Introduction
Keyboard Shortcut Identifier listens for key combinations, normalizes modifier labels for Windows, macOS, and Linux, and shows a human-readable description when the combo exists in the built-in database.
Purpose
- Learn what common shortcuts do across operating systems.
- Disambiguate Ctrl vs Cmd vs Super naming in docs.
Key Features
- OS selector pills plus auto-detect for modifier labeling (Ctrl / Cmd / Super).
- On match: title + description; optional other OS equivalents in one panel.
- Reset clears the last captured combo.
Common Use Cases
- Writing internal wiki tables (“what is Ctrl+Shift+T on Mac?”).
- Onboarding users who switch between Windows and macOS laptops.
Best Practices
- Avoid destructive combos (force quit, delete) while focused —
preventDefaultkeeps them inside the page but habits die hard. - If “unknown”, the combo may still exist in your IDE — this database covers common OS-level shortcuts only.
Comparison metrics
This tool does not output numeric benchmarks. Match vs no-match and cross-OS rows are qualitative — use consistency of labels when documenting shortcuts for teams.
