Find the
clashes
Paste your list of shortcuts and instantly spot duplicates and conflicts with system or app defaults. Perfect for power users and developers.
Nothing breaks a workflow faster than a shortcut that silently does the wrong thing. If you remap keys across tools, conflicts are inevitable. Paste your custom shortcut list and this detector highlights duplicates within your list and clashes with common system and application defaults — so you can fix the collisions before they cost you an accidental delete or misplaced action.
Features
Everything you get with this tool — free, unlimited and right in your browser.
Duplicate detection
Scan your custom list for shortcuts mapped to more than one action, so you never silently overwrite a bind.
System clash checker
Your shortcuts are compared against a built-in database of OS and app defaults — Cmd+Space, Ctrl+S and friends.
Conflict explanations
Every clash comes with a plain-language explanation and a suggested fix, so you know exactly what to remap.
Handles any format
Paste shortcuts in common formats — Ctrl+Shift+T, CMD+K, ctrl alt f — and the parser normalises them all.
How to use
Get started in a few simple steps.
Paste one shortcut per line, e.g. Ctrl+Shift+T, Cmd+K. Include the action name after a dash or tab if you like.
Press scan. The tool normalises every shortcut and compares it against your list and the system database.
Duplicates and clashes are grouped with explanations. Green items are conflict-free.
Remap the flagged shortcuts in your app, then scan again until everything is green.
Tips & recommendations
Pro tips to get the most out of this tool.
Check before you remap, not after
Run your planned binds through the detector before configuring the app. Fixing in advance saves a week of confusion.
Beware global system shortcuts
Ctrl+Shift+anything, Alt+Tab and Cmd+Space are reserved by most operating systems — the detector flags them by default.
Keep one shortcuts file
Maintain a single text file of all your binds. Paste it here every time you add something new.
Standardise the modifier order
Write Ctrl+Shift+T consistently. The normaliser handles variations, but consistency keeps your own file readable.
Examples & data

| Shortcut | Status | Note |

| Ctrl+Shift+C | Duplicate | Mapped twice in your list |
| Cmd+Space | Clash | Spotlight / app switch |
| Ctrl+Shift+T | OK | Reopen tab — safe |
Sample report output — the detector flags the same statuses you will see with your own list.
