Apple PowerBook G4 (M8980) Mac Notebook

Scrolling through web pages or large documents on a trackpad can challenge even the most nimble fingers. That's why every PowerBook G4 features a new trackpad with scrolling capability. Just drag two fingers over the trackpad to scroll vertically and horizontally or pan around any active window. Change this feature to suit your needs: Customize your trackpad settings or turn off scrolling completely via System Preferences.
