Example: Enhanced 'Scroll' action with page amounts and element-specific scrolling.

This script demonstrates the new enhanced scrolling capabilities:

1. PAGE-LEVEL SCROLLING:
   - Scrolling by specific page amounts using 'num_pages' parameter (0.5, 1.0, 2.0, etc.)
   - Scrolling up or down using the 'down' parameter
   - Uses JavaScript window.scrollBy() or smart container detection

2. ELEMENT-SPECIFIC SCROLLING:
   - NEW: Optional 'index' parameter to scroll within specific elements
   - Perfect for dropdowns, sidebars, and custom UI components
   - Uses direct scrollTop manipulation (no mouse events that might close dropdowns)
   - Automatically finds scroll containers in the element hierarchy
   - Falls back to page scrolling if no container found

3. IMPLEMENTATION DETAILS:
   - Does NOT use mouse movement or wheel events
   - Direct DOM manipulation for precision and reliability
   - Container-aware scrolling prevents unwanted side effects
