### For Developers

#### Adding New Shortcuts

To add a new shortcut, edit `app/static/keyboard-shortcuts-enhanced.js`:

```javascript
this.register('your keys', {
    name: 'Action Name',
    description: 'What this shortcut does',
    category: 'Category',
    icon: 'fa-icon-name',
    context: 'global', // or 'table', 'form', 'modal'
    action: () => {
        // Your code here
    }
}, {
    preventDefault: true,
    stopPropagation: false
});
```

#### Context Detection

The system automatically detects context. To add custom context detection, modify the `detectContext()` method:

```javascript
detectContext() {
    const activeElement = document.activeElement;

    // Check for your custom context
    if (activeElement && activeElement.closest('.your-custom-selector')) {
        this.currentContext = 'your-context';
        return;
    }

    // ... rest of detection logic
}
```

#### Registering Context-Specific Shortcuts

```javascript
this.register('Ctrl+X', {
    name: 'Custom Action',
    description: 'Only works in your context',
    category: 'Custom',
    icon: 'fa-star',
    context: 'your-context', // Important!
    action: () => {
        console.log('Context-specific action');
    }
});
```

## Integration Points

### Base Template
The shortcuts are loaded in `app/templates/base.html`:
- CSS loaded in `<head>`
- JavaScript loaded before closing `</body>`
- Available on all pages

### Command Palette
Integrates with existing command palette (`commands.js`)
- Same shortcuts accessible via palette
- Searchable command list
- Keyboard navigation

### Navigation
Works with existing navigation:
- Sidebar navigation
- Top navigation
- Breadcrumbs

## Testing

Run the test suite:

```bash
# Run all keyboard shortcuts tests
pytest tests/test_keyboard_shortcuts.py -v

# Run specific test class
pytest tests/test_keyboard_shortcuts.py::TestKeyboardShortcutsRoutes -v

# Run with coverage
pytest tests/test_keyboard_shortcuts.py --cov=app.routes.settings --cov-report=html
```

## Performance

- **JavaScript size**: ~15KB minified

## Known Limitations

1. **No Cloud Sync**: Shortcuts are stored locally in browser
2. **No Export/Import**: Cannot export/import configurations yet
3. **Fixed Key Bindings**: Full customization coming in future update
4. **Browser-Specific**: Only works in current browser/device

## Future Enhancements

Planned for future releases:
- Full key combination customization
- Cloud synchronization across devices
- Import/export shortcuts configuration
- Macro recording (multi-step shortcuts)
- Voice command integration
- Gamification (achievements for power users)

## Troubleshooting

### Shortcuts not working?
1. Check Settings → Keyboard Shortcuts
2. Ensure "Enable Keyboard Shortcuts" is on
3. Check browser console for errors
4. Try in incognito/private mode

### Conflicts with browser shortcuts?
- Some browser/OS shortcuts take precedence
- Try different key combinations
- Check browser extension conflicts

### LocalStorage issues?
- Clear browser data
- Check privacy settings
- Try regular browsing mode (not private)
