# Help System Implementation Summary

## Completed Features

### 1. Help Documentation Created
- **docs/help/index.md** - Main help page with overview and navigation
- **docs/help/shortcuts.md** - Complete keyboard shortcut reference
- **docs/help/language.md** - BASIC language reference with commands and functions
- **docs/help/examples.md** - Sample BASIC programs (Hello World, loops, games, etc.)

### 2. Help Browser Integration
- Integrated existing HelpBrowser class into curses UI
- Help browser features:
  - Markdown rendering
  - Scrollable content (↑/↓, Space, B)
  - Link navigation (Enter to follow)
  - Back navigation (U)
  - Exit (Q or ESC)

### 3. Access Methods
- **^P** (Ctrl+P) - Open help from anywhere in the editor
- **Menu → Help** - Open help from the menu system
- **^C** or **ESC** - Close help dialogs
- **Q** or **ESC** - Exit help browser

## How It Works

1. User presses ^P or selects Help from menu
2. System locates help documentation in docs/help/
3. npyscreen temporarily exits, raw curses takes over
4. HelpBrowser displays markdown-rendered content
5. User navigates with arrow keys, follows links
6. When exiting help (Q/ESC), returns to npyscreen IDE

## Testing

Automated tests confirm:
- ✓ Help opens with ^P
- ✓ Content displays correctly
- ✓ Navigation works (scroll, links)
- ✓ Exit returns to IDE cleanly
- ✓ No errors or exceptions

## Usage

```bash
python3 mbasic --ui curses yourprogram.bas
# Press ^P to open help
# Use ↑/↓ to scroll
# Press Enter on links to navigate
# Press Q or ESC to exit help
```
