## Platform-Specific Notes

### macOS

All shortcuts work as documented. Some terminals (e.g., Terminal.app) may require:
- Enabling "Use Option as Meta key" in preferences
- Allowing keyboard shortcuts in Security & Privacy settings

### Linux

All shortcuts work as documented. If using tmux/screen:
- `Ctrl+B` conflicts with tmux prefix → Consider remapping tmux
- `Ctrl+S` may freeze terminal → Disable XON/XOFF with `stty -ixon`

### Windows

All shortcuts work in Windows Terminal and modern terminals. In older terminals:
- Some `Ctrl+Shift+` combinations may not work


## Custom Shortcuts

CAI TUI currently does not support custom keyboard shortcuts. This feature may be added in future versions.

**Workaround**: Use command aliases or shell scripts for custom workflows.

## Tips for Efficiency

### Power User Workflow

1. **Keep sidebar closed** (`Ctrl+S`) for max screen space
2. **Use `Ctrl+N`/`Ctrl+B`** to switch terminals instead of mouse
3. **Master `Tab` completion** for faster command input
4. **Use `↑`** to repeat similar prompts with modifications

### Recommended Shortcuts to Memorize First

Priority 1 (Essential):
- `Ctrl+S` - Toggle sidebar
- `Ctrl+Q` - Exit
- `Ctrl+C` - Cancel agent
- `Enter` - Send prompt
- `Tab` - Autocomplete

Priority 2 (Common):
- `Ctrl+N` / `Ctrl+B` - Navigate terminals
- `Ctrl+L` - Clear screen
- `↑` / `↓` - Command history
- `ESC` - Cancel all

Priority 3 (Advanced):
- `Ctrl+E` - Close terminal
- `Ctrl+P` - Command palette

## Troubleshooting Shortcuts

### Shortcut Not Working?

**Check 1: Terminal Compatibility**
- Some shortcuts may be intercepted by your terminal emulator
- Check terminal preferences for keyboard settings
- Try a different terminal (e.g., Alacritty, iTerm2)

**Check 2: tmux/screen Conflicts**
- tmux uses `Ctrl+B` as prefix (conflicts with "Previous Terminal")
- screen uses `Ctrl+A` as prefix (no conflicts with CAI TUI)
- Consider remapping tmux prefix: `set -g prefix C-a`

**Check 3: OS-Level Shortcuts**
- Some OS keyboard shortcuts override terminal shortcuts
- Example: macOS `Ctrl+Shift+Space` opens Spotlight
- Disable conflicting OS shortcuts or use command alternatives

### Accidental Exit (`Ctrl+Q`)

If you frequently press `Ctrl+Q` by accident:

**Workaround**: Use the close session button instead
