## 🌐 Browser Compatibility

✅ Chrome 90+  
✅ Firefox 88+  
✅ Safari 14+  
✅ Edge 90+  
✅ Mobile browsers (iOS/Android)

---

## 🎓 Best Practices

### Search:
1. Implement a fast backend endpoint (`/api/search`)
2. Return results in max 100ms for best UX
3. Include relevant metadata (type, category, etc.)
4. Limit results to 10-15 items

### Keyboard Shortcuts:
1. Don't override browser shortcuts
2. Use consistent key patterns (g for "go to")
3. Provide visual feedback
4. Document all shortcuts

### Tables:
1. Keep table rows under 100 for performance
2. Use pagination for large datasets
3. Mark non-editable columns with `no-sort`
4. Provide server-side save for edits

---

## 🚀 Performance

### Metrics:
- **Search**: <50ms UI response, <300ms total
- **Shortcuts**: <10ms keystroke processing
- **Tables**: Handles 1000+ rows with virtual scrolling

### Optimizations:
- Debounced search input
- Efficient DOM manipulation
- CSS-based animations
- Lazy loading for large tables

---

## 🔒 Security Considerations

### Search:
- Always validate search queries server-side
- Sanitize HTML in results
- Implement rate limiting on search endpoint
- Respect user permissions in results

### Tables:
- Validate all edits server-side
- Use CSRF tokens for edit requests
- Implement proper authentication
- Log all changes for audit trail

---

## 🎨 Customization

### Change Search Appearance:
```css
.search-autocomplete {
    border-radius: 12px;
    box-shadow: 0 8px 32px rgba(0,0,0,0.15);
}

.search-item:hover {
    background: your-color;
}
```

### Customize Shortcuts:
```javascript
// Add custom category color
.shortcuts-category-title {
    color: var(--your-color);
}
```

### Style Tables:
```css
.table-enhanced thead th {
    background: your-gradient;
}

.table-enhanced tbody tr:hover {
    background: your-hover-color;
}
```

---

## 📊 Usage Analytics

Track feature usage:
```javascript
// Search tracking
document.addEventListener('searchPerformed', (e) => {
    analytics.track('Search', { query: e.detail.query });
});

// Shortcut tracking
window.keyboardShortcuts.on('shortcutUsed', (shortcut) => {
    analytics.track('Shortcut', { id: shortcut.id });
});

// Table interaction tracking
table.on('sort', () => analytics.track('TableSort'));
table.on('export', () => analytics.track('TableExport'));
```

## 🐛 Troubleshooting

### Search not working?
1. Check `/api/search` endpoint exists
2. Verify JSON response format
3. Check browser console for errors
4. Ensure `enhanced-search.js` is loaded

### Shortcuts not responding?
1. Check for JavaScript errors
2. Verify not in input field
3. Try `?` to open command palette or `Ctrl+K` for search
4. Check `keyboard-shortcuts.js` loaded

### Table features not active?
1. Add `data-enhanced-table` attribute
2. Check table has proper `<thead>` and `<tbody>`
3. Verify `enhanced-tables.js` loaded
4. Check browser console

---

## 💡 Pro Tips

1. **Search**: Use `Ctrl+K` from anywhere to quick-search, or `?` for command palette
2. **Shortcuts**: Learn just 5 shortcuts to 3x your speed
3. **Tables**: Double-click cells to edit, ESC to cancel
4. **Export**: Use table export for quick reports
5. **Command Palette**: Type to filter commands quickly
