+
+## Conclusion
+
+The contextual help dialog is **fully functional** and **production ready**. All features work as designed:
+
+✅ Universal keyboard support (F1)  
+✅ Context-aware binding display  
+✅ Clean, organized UI  
+✅ Smooth scrolling  
+✅ Proper categorization  
+✅ Discoverable via status bar  
+✅ No performance issues  
+
+## Recommendations
+
+1. ✅ Already implemented: F1 as primary key (universal support)
+2. ✅ Already implemented: Ctrl+? as fallback for enhanced terminals
+3. 💡 Future: Consider adding keyboard shortcut quick reference card to docs
+4. 💡 Future: Consider grouping more bindings by feature area (e.g., "Navigation", "Editing", "Session Management")
